Android USB驱动中，上层应用协议里最重要的一个文件是android/kernel/drivers/usb/gadget/android.c。这个文件实现USB的上层应用协议。

首先包含了一些系统级别的头文件，如模块、电源管理、of API等

  20.  #include <linux/init.h>
  21.  #include <linux/module.h>
  22.  #include <linux/fs.h>
  23.  #include <linux/delay.h>
  24.  #include <linux/kernel.h>
  25.  #include <linux/utsname.h>
  26.  #include <linux/platform_device.h>
  27.  #include <linux/pm_qos.h>
  28.  #include <linux/of.h>

然后是跟USB驱动本身先关的头文件

  1.  #include <linux/usb/ch9.h>
  2.  #include <linux/usb/composite.h>
  3.  #include <linux/usb/gadget.h>
  4.  #include <linux/usb/android.h>
  5.  
  6.  #include <linux/qcom/diag_dload.h>
  7.  
  8.  #include "gadget_chips.h"

然后包含了一堆实现上层USB应用协议的c文件

  1.  #include "f_fs.c"
  2.  #ifdef CONFIG_SND_PCM
  3.  #include "f_audio_source.c"
  4.  #endif
  5.  #include "f_mass_storage.c"

  38.  #include "f_ncm.c"
  39.  #include "f_charger.c"

上边的宏 CONFIG_SND_PCM 有定义，宏 CONFIG_TARGET_CORE 未定义

然后是Linux驱动中常见的宏声明，定义了作者、描述、LICENSE、版本号

  1.  MODULE_AUTHOR("Mike Lockwood");
  2.  MODULE_DESCRIPTION("Android Composite USB Driver");
  3.  MODULE_LICENSE("GPL");
  4.  MODULE_VERSION("1.0");

下面定义的变量未使用

  1. static const char longname[] = "Gadget Android";

Google自己申请的VID与PID的宏，可以在用户空间的init.**.usb.rc文件里被覆写

  1.  /* Default vendor and product IDs, overridden by userspace */
  2.  #define VENDOR_ID        0x18D1
  3.  #define PRODUCT_ID        0x0001

宏 #define ANDROID_DEVICE_NODE_NAME_LENGTH 11 定义 /sys/class/android_usb/ 下的文件节点android0之类的文件名最大长度

结构体 android_usb_function 抽象了Android自定义的用来hook Linux USB驱动框架中的相应功能的功能函数

  1.  struct android_usb_function {
  2.      char *name;
  3.      void *config;
  4.  
  5.      struct device *dev;
  6.      char *dev_name;
  7.      struct device_attribute **attributes;
  8.  
  9.      struct android_dev *android_dev;
  10.  
  11.      /* Optional: initialization during gadget bind */
  12.      int (*init)(struct android_usb_function *, struct usb_composite_dev *);
  13.      /* Optional: cleanup during gadget unbind */
  14.      void (*cleanup)(struct android_usb_function *);
  15.      /* Optional: called when the function is added the list of
  16.       *        enabled functions */
  17.      void (*enable)(struct android_usb_function *);
  18.      /* Optional: called when it is removed */
  19.      void (*disable)(struct android_usb_function *);
  20.  
  21.      int (*bind_config)(struct android_usb_function *,
  22.                 struct usb_configuration *);
  23.  
  24.      /* Optional: called when the configuration is removed */
  25.      void (*unbind_config)(struct android_usb_function *,
  26.                    struct usb_configuration *);
  27.      /* Optional: handle ctrl requests before the device is configured */
  28.      int (*ctrlrequest)(struct android_usb_function *,
  29.                      struct usb_composite_dev *,
  30.                      const struct usb_ctrlrequest *);
  31.  };

结构体 android_usb_function_holder 持有所有的当前支持的可以实现的USB设备

  1.  struct android_usb_function_holder {
  2.  
  3.      struct android_usb_function *f;
  4.  
  5.      /* for android_conf.enabled_functions */
  6.      struct list_head enabled_list;
  7.  };

结构体 android_dev 抽象了android USB gadget device，即 /sys/class/android_usb 下的 android0 等节点（目前就一个）

  1.  /**

  41.  struct android_dev {
  42.      const char *name;

  68.      /* A list node inside the android_dev_list */
  69.      struct list_head list_item;
  70.  };

结构体 android_configuration 抽象USB设备传送给HOST的配置信息

  1. struct android_configuration {
  2.     struct usb_configuration usb_config;
  3.  
  4.     /* A list of the functions supported by this config */
  5.     struct list_head enabled_functions;
  6.  
  7.     /* A list node inside the struct android_dev.configs list */
  8.     struct list_head list_item;
  9. };

下面的变量跟9006模式有关，即ramdupm（download）

  1.  struct dload_struct __iomem *diag_dload;

下面的变量是对Android USB的 /sys/class/android_usb 目录的抽象

  1.  static struct class *android_class;

下边的变量是android dev的list和数量，对应的是 /sys/class/android_usb 目录下的“android0”之类的目录

  1. static struct list_head android_dev_list;
  2. static int android_dev_count;

下边的函数在bind config和unbind config是调用

  1.  static int android_bind_config(struct usb_configuration *c);
  2.  static void android_unbind_config(struct usb_configuration *c);

下边的函数转换 usb_composite_dev 到 android_dev

  1.  static struct android_configuration *alloc_android_config
  2.                          (struct android_dev *dev);

下边的函数分配和释放Android USB设备的configuration

  1.  static struct android_configuration *alloc_android_config
  2.                          (struct android_dev *dev);
  3.  static void free_android_config(struct android_dev *dev,
  4.                  struct android_configuration *conf);

下边的函数更新PID和USB串号

  1.  static int usb_diag_update_pid_and_serial_num(uint32_t pid, const char *snum);

下边的宏和变量跟VID、PID、串号相关，会形成String表，保存在跟device string相关的变量 usb_gadget_strings 里

  1.  /* string IDs are assigned dynamically */
  2.  #define STRING_MANUFACTURER_IDX        0
  3.  #define STRING_PRODUCT_IDX        1
  4.  #define STRING_SERIAL_IDX        2
  5.  
  6.  static char manufacturer_string[];
  7.  static char product_string[];
  8.  static char serial_string[];
  9.  
  10.  /* String Table */
  11.  static struct usb_string strings_dev[] = {
  12.      [STRING_MANUFACTURER_IDX].s = manufacturer_string,
  13.      [STRING_PRODUCT_IDX].s = product_string,
  14.      [STRING_SERIAL_IDX].s = serial_string,
  15.      {  }            /* end of list */
  16.  };
  17.  
  18.  static struct usb_gadget_strings stringtab_dev = {
  19.      .language    = 0x0409,    /* en-us */
  20.      .strings    = strings_dev,
  21.  };
  22.  
  23.  static struct usb_gadget_strings *dev_strings[] = {
  24.      &stringtab_dev,
  25.      NULL,
  26.  };

下边的结构体抽象出发送给HOST的USB设备描述符，可以通过文件节点 /sys/class/android_usb/android0 下的相应节点来查看和改变

  1.  static struct usb_device_descriptor device_desc = {
  2.      .bLength              = sizeof(device_desc),
  3.      .bDescriptorType      = USB_DT_DEVICE,
  4.      .bcdUSB               = __constant_cpu_to_le16(0x0200),
  5.      .bDeviceClass         = USB_CLASS_PER_INTERFACE,
  6.      .idVendor             = __constant_cpu_to_le16(VENDOR_ID),
  7.      .idProduct            = __constant_cpu_to_le16(PRODUCT_ID),
  8.      .bcdDevice            = __constant_cpu_to_le16(0xffff),
  9.      .bNumConfigurations   = ,
  10.  };

下边的结构体抽象出跟USB OTG相关的描述符，使用OTG，手机进入HOST模式

  1.  static struct usb_otg_descriptor otg_descriptor = {
  2.      .bLength =        sizeof otg_descriptor,
  3.      .bDescriptorType =    USB_DT_OTG,
  4.      .bmAttributes =        USB_OTG_SRP | USB_OTG_HNP,
  5.      .bcdOTG               = __constant_cpu_to_le16(0x0200),
  6.  };
  7.  
  8.  static const struct usb_descriptor_header *otg_desc[] = {
  9.      (struct usb_descriptor_header *) &otg_descriptor,
  10.      NULL,
  11.  };

枚举 android_device_state 描述设备的状态，有断开连接，连接，配置好，挂起，恢复 。工作时的状态是配置好

  1.  enum android_device_state {
  2.      USB_DISCONNECTED,
  3.      USB_CONNECTED,
  4.      USB_CONFIGURED,
  5.      USB_SUSPENDED,
  6.      USB_RESUMED
  7.  };

下边的init函数在模块初始化时调用

  1.  static int __init init(void)
  2.  {
  3.      int ret;
  4.  
  5.      INIT_LIST_HEAD(&android_dev_list);
  6.      android_dev_count = ;
  7.  
  8.      ret = platform_driver_register(&android_platform_driver);
  9.      if (ret) {
  10.          pr_err("%s(): Failed to register android"
  11.                   "platform driver\n", __func__);
  12.      }
  13.  
  14.      /* HACK: exchange composite's setup with ours */
  15.      composite_setup_func = android_usb_driver.gadget_driver.setup;
  16.      android_usb_driver.gadget_driver.setup = android_setup;
  17.      composite_suspend_func = android_usb_driver.gadget_driver.suspend;
  18.      android_usb_driver.gadget_driver.suspend = android_suspend;
  19.      composite_resume_func = android_usb_driver.gadget_driver.resume;
  20.      android_usb_driver.gadget_driver.resume = android_resume;
  21.  
  22.      return ret;
  23.  }
  24.  late_initcall(init);

首先，初始化Android设备list android_dev_list 和Android设备数 android_dev_count 为0，然后注册platform driver android_platform_driver 。最后，hook Linux USB驱动框架的复口USB驱动的setup、suspend、resume函数为本文件中定义的android_*****函数。变量 android_usb_driver 为 usb_composite_driver 类型结构体，用来hook系统的usb_composite框架下的相关函数，定义如下

  1.  static struct usb_composite_driver android_usb_driver = {
  2.      .name        = "android_usb",
  3.      .dev        = &device_desc,
  4.      .strings    = dev_strings,
  5.      .bind        = android_bind,
  6.      .unbind        = android_usb_unbind,
  7.      .disconnect    = android_disconnect,
  8.      .max_speed    = USB_SPEED_SUPER
  9.  };

本文件中的platform_driver相关配置如下，字符串 "android_usb_hsic" 没用到

  1.  static const struct platform_device_id android_id_table[] = {
  2.      {
  3.          .name = "android_usb",
  4.      },
  5.      {
  6.          .name = "android_usb_hsic",
  7.      },
  8.  };
  9.  
  10.  static struct of_device_id usb_android_dt_match[] = {
  11.      {    .compatible = "qcom,android-usb",
  12.      },
  13.      {}
  14.  };
  15.  
  16.  static struct platform_driver android_platform_driver = {
  17.      .driver = {
  18.          .name = "android_usb",
  19.          .of_match_table = usb_android_dt_match,
  20.      },
  21.      .probe = android_probe,
  22.      .remove = android_remove,
  23.      .id_table = android_id_table,
  24.  };

probe函数如下，主要作用是分配相应私有、全局的data、list、mutex等变量，读取dts中的配置，设置到相应的结构体里去，在 /sys/class 下添加文件目录节点 ，将自身的驱动probe到usb composite框架中，并设置休眠唤醒参数。

  1.  static int android_probe(struct platform_device *pdev)
  2.  {
  3.      struct android_usb_platform_data *pdata;
  4.      struct android_dev *android_dev;

  13.              return -ENOMEM;
  14.          }

  18.                  &pdata->swfi_latency);
  19.  
  20.          len = of_property_count_strings(pdev->dev.of_node,
  21.                  "qcom,streaming-func");
  22.          if (len > MAX_STREAMING_FUNCS) {
  23.              pr_err("Invalid number of functions used.\n");
  24.              return -EINVAL;
  25.          }
  26.  
  27.          for (i = ; i < len; i++) {
  28.              const char *name = NULL;
  29.  
  30.              of_property_read_string_index(pdev->dev.of_node,
  31.                  "qcom,streaming-func", i, &name);
  32.  
  33.              if (!name)
  34.                  continue;
  35.  
  36.              if (sizeof(name) > FUNC_NAME_LEN) {
  37.                  pr_err("Function name is bigger than allowed.\n");
  38.                  continue;
  39.              }
  40.  
  41.              strlcpy(pdata->streaming_func[i], name,
  42.                  sizeof(pdata->streaming_func[i]));
  43.              pr_debug("name of streaming function:%s\n",
  44.                  pdata->streaming_func[i]);
  45.          }
  46.  
  47.          pdata->streaming_func_count = len;
  48.  
  49.          pdata->cdrom = of_property_read_bool(pdev->dev.of_node,
  50.              "qcom,android-usb-cdrom");

结构体 android_usb_platform_data 是android usb platform driver的dev的private data。其定义位于androd/kerenl/include/linux/usb/andriod.h文件中，这文件首先包含了usb复口头文件composite.h

  17.  #ifndef    __LINUX_USB_ANDROID_H
  18.  #define    __LINUX_USB_ANDROID_H
  19.  
  20.  #include <linux/usb/composite.h>

然后定义了结构体 android_usb_platform_data 及其中数组的最大范围用到的宏

  1.  #define MAX_STREAMING_FUNCS 3
  2.  #define FUNC_NAME_LEN 10
  1.  struct android_usb_platform_data {
  2.      int (*update_pid_and_serial_num)(uint32_t, const char *);
  3.      u32 pm_qos_latency[MAX_VOTES];
  4.      u8 usb_core_id;
  5.      char streaming_func[MAX_STREAMING_FUNCS][FUNC_NAME_LEN];
  6.      int  streaming_func_count;
  7.      u8 uicc_nluns;
  8.      bool cdrom;
  9.  };

回到 android_probe 函数，若相应的dev有of_node,即在dts中有定义，则获取相应的配置。Android USB在dts中的配置位于android/kernel/arc/arm（或arm64，都一样，arm64中的qcom目录是对arm的软链接）/boot/dts/qcom目录下的msm8916.dtsi和msm8916-qrd.dtsi中，内容如下

  1.      android_usb: android_usb@086000c8 {
  2.          compatible = "qcom,android-usb";
  3.          reg = <0x086000c8 0xc8>;
  4.          qcom,android-usb-swfi-latency = <>;
  5.          qcom,streaming-func = "mtp";
  6.          qcom,android-usb-uicc-nluns = /bits/  <>;
  7.      };
  1.  &android_usb {
  2.      qcom,android-usb-cdrom;
  3.  };

首先通过 devm_kzalloc 函数为相应dev的private指针分配内存，其类型为 android_usb_platform_data 。

然后读出 qcom,android-usb-swfi-latency ，其值用在 pm_qos_update_request 函数中来定义投票级别，默认值是1。

然后读出 qcom,streaming-func 的个数，并在循环中读出stream func，传给platform data里的 streaming_func 和 streaming_func_count 中，这里的值只有一个"mtp"。

然后读出 qcom,android-usb-cdrom ，根据其存在与否决定是否支持CDROM。

最后读出 qcom,android-usb-uicc-nluns ，其在dtsi中的写法规定其占8位，即一个字节，默认值为1。

若不存在dts文件，则用传统的platform_device。

在配置好platform_data后，则调用 class_create 函数创建 /sys/class 下的文件节点。

然后分配 android_dev 的内存，有dev的name、disable的深度、支持的USB功能、配置的数量、初始化configs list和work对了，配置其执行函数为 android_work 、初始化相应的mutex、设定之前分配的pdata。添加list_item到全局的 android_dev_list 中，并将 android_dev_count 加1。

支持的USB功能在变量 supported_functions 数组中，其类型为 android_usb_function ，内容如下

  1.  static struct android_usb_function *supported_functions[] = {
  2.      &ffs_function,
  3.      &mbim_function,
  4.      &ecm_qc_function,
  5.  #ifdef CONFIG_SND_PCM
  6.      &audio_function,
  7.  #endif
  8.      &rmnet_smd_function,
  9.      &rmnet_function,
  10.      &gps_function,
  11.      &diag_function,
  12.      &qdss_function,
  13.      &serial_function,
  14.      &ccid_function,
  15.      &acm_function,
  16.      &mtp_function,
  17.      &ptp_function,
  18.      &rndis_function,
  19.      &rndis_qc_function,
  20.      &ecm_function,
  21.      &ncm_function,
  22.      &mass_storage_function,
  23.      &accessory_function,
  24.  #ifdef CONFIG_SND_PCM
  25.      &audio_source_function,
  26.  #endif
  27.      &uasp_function,
  28.      &charger_function,
  29.      NULL
  30.  };

各个具体的功能定义如下。

  2.      .name        = "ffs",
  3.      .init        = ffs_function_init,

然后申请分配给USB的IO空间地址，即 reg = <0x086000c8 0xc8>; ，获取到后分配给 diag_dload 。

然后调用 andriod_create_device 函数，创建sys下的文件节点，比如 /sys/class/android_usb/android0之类的 ， android_dev_list 中的单项就对应这个， usb_core_id 为0（因为 devm_kzalloc 里有个“z”，即用0初始化分配的内存）。

  14.      dev->dev = device_create(android_class, NULL,
  15.                      MKDEV(, ), NULL, device_node_name);
  16.      if (IS_ERR(dev->dev))
  17.          return PTR_ERR(dev->dev);
  18.  
  19.      dev_set_drvdata(dev->dev, dev);
  20.  
  21.      while ((attr = *attrs++)) {
  22.          err = device_create_file(dev->dev, attr);
  23.          if (err) {
  24.              device_destroy(android_class, dev->dev->devt);
  25.              return err;
  26.          }
  27.      }
  28.      return ;
  29.  }

初始化相应节点的名字后，调用 device_create 函数创建节点 /sys/class/android_usb/android0 ，并设置创造出来的文件节点的dev的private data为dev。

然后在循环里在创造出来的目录下创建更多的节点，这些节点的定义位于 android_usb_attributes 。若有错误，则销毁目录 /sys/class/android_usb/android0  。

android_usb_attributes 内容如下

  1.  static struct device_attribute *android_usb_attributes[] = {
  2.      &dev_attr_idVendor,
  3.      &dev_attr_idProduct,
  4.      &dev_attr_bcdDevice,
  5.      &dev_attr_bDeviceClass,
  6.      &dev_attr_bDeviceSubClass,
  7.      &dev_attr_bDeviceProtocol,
  8.      &dev_attr_iManufacturer,
  9.      &dev_attr_iProduct,
  10.      &dev_attr_iSerial,
  11.      &dev_attr_functions,
  12.      &dev_attr_enable,
  13.      &dev_attr_pm_qos,
  14.      &dev_attr_state,
  15.      &dev_attr_remote_wakeup,
  16.      NULL
  17.  };

实现这些文件节点是通过宏 DESCRIPTOR_ATTR 和 DESCRIPTOR_STRING_ATTR 自动实现相应节点的show和store函数的，这两个宏如下

  1.  #define DESCRIPTOR_ATTR(field, format_string)                \
  2.  static ssize_t                                \
  3.  field ## _show(struct device *dev, struct device_attribute *attr,    \
  4.          char *buf)                        \
  5.  {                                    \
  6.      return snprintf(buf, PAGE_SIZE,                    \
  7.              format_string, device_desc.field);        \
  8.  }                                    \
  9.  static ssize_t                                \
  10.  field ## _store(struct device *dev, struct device_attribute *attr,    \
  11.          const char *buf, size_t size)                \
  12.  {                                    \
  13.      int value;                            \
  14.      if (sscanf(buf, format_string, &value) == ) {            \
  15.          device_desc.field = value;                \
  16.          return size;                        \
  17.      }                                \
  18.      return -;                            \
  19.  }                                    \
  20.  static DEVICE_ATTR(field, S_IRUGO | S_IWUSR, field ## _show, field ## _store);
  21.  
  22.  #define DESCRIPTOR_STRING_ATTR(field, buffer)                \
  23.  static ssize_t                                \
  24.  field ## _show(struct device *dev, struct device_attribute *attr,    \
  25.          char *buf)                        \
  26.  {                                    \
  27.      return snprintf(buf, PAGE_SIZE, "%s", buffer);            \
  28.  }                                    \
  29.  static ssize_t                                \
  30.  field ## _store(struct device *dev, struct device_attribute *attr,    \
  31.          const char *buf, size_t size)                \
  32.  {                                    \
  33.      if (size >= sizeof(buffer))                    \
  34.          return -EINVAL;                        \
  35.      strlcpy(buffer, buf, sizeof(buffer));                \
  36.      strim(buffer);                            \
  37.      return size;                            \
  38.  }                                    \
  39.  static DEVICE_ATTR(field, S_IRUGO | S_IWUSR, field ## _show, field ## _store);

相应宏的定义如下

  1.  DESCRIPTOR_ATTR(idVendor, "%04x\n")
  2.  DESCRIPTOR_ATTR(idProduct, "%04x\n")
  3.  DESCRIPTOR_ATTR(bcdDevice, "%04x\n")
  4.  DESCRIPTOR_ATTR(bDeviceClass, "%d\n")
  5.  DESCRIPTOR_ATTR(bDeviceSubClass, "%d\n")
  6.  DESCRIPTOR_ATTR(bDeviceProtocol, "%d\n")
  7.  DESCRIPTOR_STRING_ATTR(iManufacturer, manufacturer_string)
  8.  DESCRIPTOR_STRING_ATTR(iProduct, product_string)
  9.  DESCRIPTOR_STRING_ATTR(iSerial, serial_string)

节点functions、enable、pm_qos、state、remote_wakeup的定义如下

  1.  static DEVICE_ATTR(functions, S_IRUGO | S_IWUSR, functions_show,
  2.                           functions_store);
  3.  static DEVICE_ATTR(enable, S_IRUGO | S_IWUSR, enable_show, enable_store);
  4.  static DEVICE_ATTR(pm_qos, S_IRUGO | S_IWUSR,
  5.          pm_qos_show, pm_qos_store);
  6.  static DEVICE_ATTR(state, S_IRUGO, state_show, NULL);
  7.  static DEVICE_ATTR(remote_wakeup, S_IRUGO | S_IWUSR,
  8.          remote_wakeup_show, remote_wakeup_store);

然后 usb_composite_probe 函数会被手动调用，加载 android_usb_driver 。
最后发送添加pm qos请求，并设置 pm_qos 为“High”，返回结果为0。

函数的最后有 "error_probe","err_dev","err_alloc" 三个标签，处理不同阶段的错误。

再看退出相关的函数

先是注册移除函数

  1.  static void __exit cleanup(void)
  2.  {
  3.      platform_driver_unregister(&android_platform_driver);
  4.  }
  5.  module_exit(cleanup);

然后 android_remove 函数被框架自动调用

  1.  static int android_remove(struct platform_device *pdev)
  2.  {
  3.      struct android_dev *dev = NULL;
  4.      struct android_usb_platform_data *pdata = pdev->dev.platform_data;
  5.      int usb_core_id = ;
  6.  
  7.      if (pdata)
  8.          usb_core_id = pdata->usb_core_id;
  9.  
  10.      /* Find the android dev from the list */
  11.      list_for_each_entry(dev, &android_dev_list, list_item) {
  12.          if (!dev->pdata)
  13.              break; /*To backward compatibility*/
  14.          if (dev->pdata->usb_core_id == usb_core_id)
  15.              break;
  16.      }
  17.  
  18.      if (dev) {
  19.          android_destroy_device(dev);
  20.          if (pdata && pdata->swfi_latency)
  21.              pm_qos_remove_request(&dev->pm_qos_req_dma);
  22.          list_del(&dev->list_item);
  23.          android_dev_count--;
  24.          kfree(dev);
  25.      }
  26.  
  27.      if (list_empty(&android_dev_list)) {
  28.          class_destroy(android_class);
  29.          android_class = NULL;
  30.          usb_composite_unregister(&android_usb_driver);
  31.      }
  32.  
  33.      return ;
  34.  }

先是遍历 android_dev_list ，相应的 dev 的 pdata 为空或者 usb_core_id 相同时就打断循环，调用 android_destroy_device 销毁设备，要是 swfi_latency 不为0的话，移除pm qos请求，在列表中删除这个 dev ， android_dev_count 减1，释放相应 dev 的内存。

android_destroy_device 函数如下

  1.  static void android_destroy_device(struct android_dev *dev)
  2.  {
  3.      struct device_attribute **attrs = android_usb_attributes;
  4.      struct device_attribute *attr;
  5.  
  6.      while ((attr = *attrs++))
  7.          device_remove_file(dev->dev, attr);
  8.      device_destroy(android_class, dev->dev->devt);
  9.  }

可以看到，其功能就是删除目录 /sys/class/android_usb/android0 下的文件节点和目录本身。

若 android_dev_list 为空的话，就销毁目录 /sys/class/android_usb ，并调用函数 usb_composite_unregister 移除 android_usb_driver ，最后返回0。

当用USB线把Android设备与HOST连接时，Android设备会枚举自己。（挖坑）

先说下USB协议的基础知识。

显示USB描述符。

USB协议为USB设备定义了一套描述设备功能和属性的有固定结构的描述符，包括标准的描述符即设备描述符、配置描述符、接口描述符、端点描述符和字符串描述符，还有非标准描述符，如类描述符等。USB设备通过这些描述符向USB主机汇报设备的各种各样属性，主机通过对这些描述符的访问对设备进行类型识别、配置并为其提供相应的客户端驱动程序。

USB设备通过描述符反映自己的设备特性。USB描述符是由特定格式排列的一组数据结构组成。

在USB设备枚举过程中，主机端的协义软件需要解析从USB设备读取的所有描述符信息。在USB主向设备发送读取描述符的请求后，USB设备将所有的描述符以连续的数据流方式传输给USB主机。主机从第一个读到的字符开始，根据双方规定好的数据格式，顺序地解析读到的数据流。

USB描述符包含标准描述符、类描述符和厂商特定描述３种形式。任何一种设备必须提供USB标准描述符（对字符串描述符可例外）。

在USB1.X中，规定了5种标准描述符：设备描述符（Device Descriptor)、配置描述符（Configuration Descriptor）、接口描述符（Interface Descriptor）、端点描述符（Endpoint Descriptor）和字符串描述符（String Descriptor）。

每个USB设备只有一个设备描述符，而一个设备中可包含一个或多个配置描述符，即USB设备可以有多种配置（物理特性，如供电）。设备的每一个配置中又可以包含一个或多个接口描述符，即USB设备可以支持多种功能（接口），接口的特性通过描述符提供。每一个接口描述符包含多个端点描述符，端点是USB通信的最基本形式，每一个USB设备接口在主机看来就是一个端点的集合。主机只能通过端点与设备进行通信，以使用设备的功能。在USB系统中每一个端点都有惟一的地址，这是由设备地址和端点号给出的。每个端点都有一定的属性，其中包括传输方式、总线访问频率、带宽、端点号和数据包的最大容量等。一个USB端点只能在一个方向承载数据，或者从主机到设备（称为输出端点），或者从设备到主机（称为输入端点），因此端点可看作一个单向的管道。端点0通常为控制端点，用于设备初始化参数等。只要设备连接到USB上并且上电端点0就可以被访问。端点1、2等一般用作数据端点，存放主机与设备间往来的数据。

在USB主机访问USB设备的描述符时，USB设备依照设备描述符、配置描述符、接口描述符、端点描述符、字符串描述符顺序将所有描述符传给主机。一设备至少要包含设备描述符、配置描述符和接口描述符，如果USB设备没有端点描述符，则它仅仅用默认管道与主机进行数据传输。

总体而言，USB设备非常复杂，由许多不同的逻辑单元组成，如图1、图2所示，这些单元之间的关系如下：

图1

图2

l 设备通常有一个或多个配置；

l 配置通常有一个或多个接口；

l 接口通常有一个或多个设置；

l 接口有零或多个端点。

这种层次化配置信息在设备中通过一组标准的描述符来描述，如下所示。

  1. 设备描述符：关于设备的通用信息，如供应商ID、产品ID和修订ID，支持的设备类、子类和适用的协议以及默认端点的最大包大小等。在Linux内核中，USB设备用 usb_device 结构体来描述，USB设备描述符定义为 usb_device_descriptor 结构体，其定义如下

    1.   struct usb_device_descriptor
    2.   {
    3.   _ _u8  bLength; //描述符长度
    4.   _ _u8  bDescriptorType; //描述符类型编号
    5.  
    6.   _ _le16 bcdUSB; //USB版本号
    7.   _ _u8  bDeviceClass; //USB分配的设备类code
    8.   _ _u8  bDeviceSubClass;// USB分配的子类code
    9.   _ _u8  bDeviceProtocol; //USB分配的协议code
    10.  _ _u8  bMaxPacketSize0; //endpoint0最大包大小
    11.  _ _le16 idVendor; //厂商编号
    12.  _ _le16 idProduct; //产品编号
    13.  _ _le16 bcdDevice; //设备出厂编号
    14.  _ _u8  iManufacturer; //描述厂商字符串的索引
    15.  _ _u8  iProduct; //描述产品字符串的索引
    16.  _ _u8  iSerialNumber; //描述设备序列号字符串的索引
    17.  _ _u8  bNumConfigurations; //可能的配置数量
    18.  } _ _attribute_ _ ((packed));
  2. 配置描述符：此配置中的接口数、支持的挂起和恢复能力以及功率要求。USB配置在内核中使用 usb_host_config 结构体描述，USB配置描述符定义为结构体 usb_config_descriptor ，其定义如下 
    1.   struct usb_config_descriptor
    2.   {
    3.   _ _u8  bLength; //描述符长度
    4.   _ _u8  bDescriptorType; //描述符类型编号
    5.  
    6.   _ _le16 wTotalLength; //配置所返回的所有数据的大小
    7.   _ _u8  bNumInterfaces; // 配置所支持的接口数
    8.   _ _u8  bConfigurationValue; //Set_Configuration命令需要的参数值
    9.   _ _u8  iConfiguration; //描述该配置的字符串的索引值
    10.  _ _u8  bmAttributes; //供电模式的选择
    11.  _ _u8  bMaxPower; //设备从总线提取的最大电流
    12.  } _ _attribute_ _ ((packed));
  3. 接口描述符：接口类、子类和适用的协议，接口备用配置的数目和端点数目。USB接口在内核中使用 usb_interface 结构体描述，USB接口描述符定义为结构体 usb_interface_descriptor ，其定义如下 
    1.   struct usb_interface_descriptor
    2.   {
    3.   _ _u8  bLength;           //描述符长度
    4.   _ _u8  bDescriptorType; //描述符类型
    5.  
    6.   _ _u8  bInterfaceNumber;   // 接口的编号
    7.   _ _u8  bAlternateSetting; //备用的接口描述符编号
    8.   _ _u8  bNumEndpoints;      //该接口使用的端点数，不包括端点0
    9.   _ _u8  bInterfaceClass;    //接口类型
    10.  _ _u8  bInterfaceSubClass; //接口子类型
    11.  _ _u8  bInterfaceProtocol; //接口所遵循的协议
    12.  _ _u8  iInterface; //描述该接口的字符串索引值
    13.  } _ _attribute_ _ ((packed));
  4. 端点描述符：端点地址、方向和类型，支持的最大包大小，如果是中断类型的端点则还包括轮询频率。在Linux内核中，USB端点使用 usb_host_endpoint 结构体来描述，USB端点描述符定义为 usb_endpoint_descriptor 结构体，其定义如下 
    1.   struct usb_endpoint_descriptor
    2.   {
    3.   _ _u8  bLength; //描述符长度
    4.   _ _u8  bDescriptorType; //描述符类型
    5.  _ _u8  bEndpointAddress; //端点地址：0～3位是端点号，第7位是方向(0-OUT,1-IN)
    6.  _ _u8  bmAttributes; //端点属性：bit[0:1] 的值为00表示控制，为01表示同步，为02表示批量，为03表示中断
    7.   _ _le16 wMaxPacketSize; //// 本端点接收或发送的最大信息包的大小
    8.   _ _u8  bInterval;//轮询数据传送端点的时间间隔
    9.                        //对于批量传送的端点以及控制传送的端点，此域忽略
    10.                      //对于同步传送的端点，此域必须为1
    11.                      //对于中断传送的端点，此域值的范围为1～255
    12.  _ _u8  bRefresh;
    13.  _ _u8  bSynchAddress;
    14.  } _ _attribute_ _ ((packed));
  5. 字符串描述符：在其他描述符中会为某些字段提供字符串索引，它们可被用来检索描述性字符串，可以以多种语言形式提供。字符串描述符是可选的，有的设备有，有的设备没有，字符串描述符对应于 usb_string_descriptor 结构体，其定义如下 
    1.  struct usb_string_descriptor
    2.  {
    3.  _ _u8  bLength; //描述符长度
    4.  _ _u8  bDescriptorType; //描述符类型
    5.  
    6.  _ _le16 wData[];/* 以UTF-16LE编码 */
    7.  } _ _attribute_ _ ((packed));

插入一个SanDisk U盘后，可以通过lsusb命令得到这个U盘相关的描述符，从中可以显示这个U盘包含了一个设备描述符、一个字符串描述符、一个配置描述符、一个接口描述符以及批量输入和批量输出两个端点描述符。呈现出来的信息内容直接对应于 usb_device_descriptor、usb_config_descriptor、usb_interface_descriptor、usb_endpoint_descriptor、usb_string_descriptor 结构体，其内容如下所示。

当用户点击相应USB选项或者本质上， sys.usb.config 被设置时，会写 /sys/class/android_usb/android0 下的一系列节点，触发一系列的动作。

以配置为 “mtp,adb” 和 ptp,adb 为例，其在init.qcom.usb.rc文件中的配置如下

  1. on property:sys.usb.config=mtp,adb
  2.     stop adbd
  3.     write /sys/class/android_usb/android0/enable

可以看到，不管插不插usb线，都会走的调用流程如下：


init->android_probe->android_create_device->android_bind->android_init_functions


之后就是匹配rc文件里的相关配置，向各个文件节点写入响应的数值。


下面具体分析各个流程，从相关文件节点的读写相应函数开始分析。


先看enable时写0和1内核驱动的动作
