基于安卓的rndis驱动的usb网络共享的实现

开发环境：

硬件;三星s5pv210 

软件;linux3.0.8内核(用于android)

文件系统;嵌入式qt文件系统

内核配置

                --- USB Gadget Support                                                                        | |

  | |                        <*>   S3C high speed(2.0, dual-speed) USB OTG device                                          | |  

  | |                                S3C OTGD transfer mode (enabled DMA MODE)  --->                                       | |  
  | |                        <*>   USB Gadget Drivers (Android Gadget)  --->                                               | |  

  | |                                Android Gadget                                                                        | |  

  | |                        [*]       Use double word aligned                                                             | |  

  | |                                                                                   

注意：210平台的这个内核必须勾选Use double word aligned，否则网络通不了.

启动脚本配置

#/bin/sh

echo LGE > /sys/class/android_usb/adroid0/f_rndis/manufacturer

echo 18d1 > /sys/class/android_usb/android0/f_rndis/vendorID

echo 1 > /sys/class/android_usb/android0/f_rndis/wceis

echo 0 > /sys/class/android_usb/android0/enable

echo 18d1 > /sys/class/android_usb/android0/idVendor

echo 4ee4 > /sys/class/android_usb/android0/idProduct

echo 239 > /sys/class/android_usb/android0/bDeviceClass

echo 2 > /sys/class/android_usb/android0/bDeviceSubClass

echo 1 > /sys/class/android_usb/android0/bDeviceProtocol

echo rndis,mass_storage > /sys/class/android_usb/android0/functions

echo /dev/mmcblk1p1 > /sys/class/android_usb/android0/f_mass_storage/lun/file

echo 1 > /sys/class/android_usb/android0/enable

sleep 1

ifconfig rndis0 down

ifconfig rndis0 192.168.8.1 up

执行完毕上述脚本，即实现了rndis,和U盘的2个功能，如果需要实现开启usb的其他功能，参见下面的说明
