      3G模块设备和Android系统主要通过USB接口进行数据通信。Android系统上的Linux内核需要根据3G模块设备上报的USB设备接口加载USB
驱动，USB驱动正确加载后，3G模块才能正常工作。下面以添加华为模块设备识别为例：
 
一、修改 .../kernel/drivers/usb/serial/option.c文件
    1、在option_probe（）函数内添加红色框部分语句，可以支持 selective  suspend 特性。
         
    2、在 option_driver（）函数中添加红色框部分语句，增加对reset_resume函数的调用。
         
    3、增加对新PID的支持，添加红色框部分语句。
         
    4、在static  const  struct  usb_device_id  option_ids[ ] 增加华为所有的模块 ID，语句如下：
         
	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0xff, 0xff) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x01, 0x01) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x01, 0x02) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x01, 0x03) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x01, 0x04) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x01, 0x05) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x01, 0x06) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x01, 0x0A) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x01, 0x0B) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x01, 0x0C) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x01, 0x0D) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x01, 0x0E) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x01, 0x0F) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x01, 0x10) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x01, 0x12) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x01, 0x13) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x01, 0x14) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x01, 0x15) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x01, 0x16) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x01, 0x31) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x01, 0x32) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x01, 0x33) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x01, 0x34) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x01, 0x35) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x01, 0x36) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x01, 0x3A) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x01, 0x3B) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x01, 0x3C) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x01, 0x3D) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x01, 0x3E) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x01, 0x3F) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x01, 0x46) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x02, 0x01) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x02, 0x02) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x02, 0x03) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x02, 0x04) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x02, 0x05) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x02, 0x06) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x02, 0x0A) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x02, 0x0B) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x02, 0x0C) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x02, 0x0D) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x02, 0x0E) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x02, 0x0F) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x02, 0x10) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x02, 0x12) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x02, 0x13) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x02, 0x14) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x02, 0x15) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x02, 0x16) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x02, 0x31) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x02, 0x32) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x02, 0x33) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x02, 0x34) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x02, 0x35) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x02, 0x36) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x02, 0x3A) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x02, 0x3B) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x02, 0x3C) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x02, 0x3D) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x02, 0x3E) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x02, 0x3F) }, 	{ HW_USB_DEVICE_AND_INTERFACE_INFO(HUAWEI_VENDOR_ID, 0xff, 0x02, 0x46) },

二、修改 .../kernel/drivers/usb/serial/usb_wwan.c文件
    1、添加对BCDUSB值和对华为vid值的定义，红色框部分语句：
         
    2、先在usb_wwan_write（）函数中添加：struct  usb_host_endpoint  *ep 定义；
         再添加增加对零包的判断，添加红框部分语句：
         
    到此，重新编译镜像，华为的3G模块就能识别了，如果上面注册的ID没有你使用的华为3G模块，在static const struct usb_device_id option_ids[ ]里面自行添加即可。
 
附：如果怕麻烦，还可以这样添加，以中兴MG3732模块为例。（系统支持中兴其他模块型号，只不过没有注册你的模块型号）
      MG3732           VID：0x19d2       PID ：0xffeb   （模块ID必须知道）
      只需在.../kernel/drivers/usb/serial/option.c文件中增加如下红色框部分语句即可：
