1、一、环境1、 开发板内核：linux-2.6.28-omap2、 3G卡片：华为E1750二、相关工具1        usb-modeswitch-1.0.2.tar.bz2usb_modeswitch这个工具来进行3G模式转换2libusb-0.1.12.tar.gzlibusb提供给usb_modeswitch一套系统API三、交叉编译1．交叉编译libusb解压并进入libusb-0.1.12目录，建立子目录install用于存放最后生存的库文件与头文件。[root@libusb-0.1.12]#

2、mkdirinstall配置并生成Makefile文件[root@libusb-0.1.12]#./configure--build=i686-linux--host=arm-none-linux-gnueabi--prefix=/home/libusb-0.1.12/install[root@libusb-0.1.12]#make[root@libusb-0.1.12]#makeinstall（我的交叉编译器是arm-none-linux-gnueabi，你的可能是arm-linux）2.交叉编译usb

3、_modeswitch（1）修改Makefile文件CC=arm-none-linux-gnueabi（2）将libusb里的库头文件拷到交叉编译器的include和lib目录下（3）make（4）修改usb_modeswitch-1.0.2目录下的usb_modeswitch.conf文件#HuaweiE1750DefaultVendor=0x12d1DefaultProduct=0x1446 TargetVendor=0x12d1TargetProduct=0x1001 #onlyforreferen

5、driver/usb/serial/option.c中加入3G卡片的ID信息：#defineHUAWEI_PRODUCT_E17500x1446Makemenuconfig选上编译这个文件的选项修改文件drivers/usb/storage/unusual_devs.h,去掉对移植网卡ID的屏蔽，关于此官方是这样说的：KernelrelatedissuesInsomenewerkernels,certaindevicefamilies(someOption,someHuawei,someZTEasment
