在ARM上安装USB无线网卡驱动过程（8188eu）
1、首先在下载对应的驱动源码包：
下载地址：http://download.csdn.net/detail/zzz_mraz/5262010
2. 解压该文件夹：tar xvzf rtl8188eu_USB_linux.tar.gz
3. 进入给文件夹修改Makefile文件。
修改如下：
a、平台选择：CONFIG_PLATFORM_I386_PC = n CONFIG_PLATFORM_ARM_S3C2K4 = y
b、修改使用的编译工具、对应的内核目录：
- ifeq ($(CONFIG_PLATFORM_ARM_S3C2K4), y)
- EXTRA_CFLAGS += -DCONFIG_LITTLE_ENDIAN
- ARCH := arm
- CROSS_COMPILE := /usr/local/arm/4.2.2-eabi/usr/bin/arm-linux-
- # KVER := 2.6.24.7_$(ARCH)
- KSRC := /home/uni/workspace/20141107_yisuo/linux_3_6/linux-3.6
- endif
主要修改KVER:=2.6.38
KSRC :=/opt/FriendlyARM/mini6410/linux/linux-2.6.38
配置好上述选项，make后就得到驱动模块：8192cu.ko
生成8188.ko文件后，将其下载到mini6410开发板上，拷贝到/home文件夹下
2、模块加载：
执行insmod 8188eu.ko可以看到如下信息：
