硬件平台 FS9200 开发板
os:  linux 2.6.13
ralink 无线包：2008_0506_RT73_Linux_STA_Drv1.1.0.1

思路：用arm-linux-gcc 编译rt73.ko ,原后copy到rootfs的lib/modules中，同样相关配置文件也一同拷入，可以insmod上模块

详细过程：
1 .Makefile修改于下，

#       cp $(shell pwd)/*.bin /lib/firmware/ ;

config:
        @touch config.mk
        @./Configure

2。make all
3 . make install后生成myroot.cfamfs
4.同时修改内核的配置。重新编译生成新的zImage
#
# Wireless LAN (non-hamradio)
#
CONFIG_NET_RADIO=y

5.下载zImag,myroot.cfamfs到板子上，运行insmod rt73.ko,正常加载
/etc/init.d # lsmod            
Module                  Size  Used by    Not tainted
rt73 237688 0 - Live 0xbf000000

6。ifconfig  rausb0 会出现下列问题
/etc/init.d # ifconfig rausb0               
ifconfig: rausb0: error fetching interface information: Device not found

/etc/init.d #
/etc/init.d # ifconfig rausb0 inet 192.168.0.100 up
SIOCSIFADDR: No such device
SIOCGIFFLAGS: No such device

分析 ：板子无法找到rausb0设备，我试着用遍入内核的方法，还是出现同样的问题？网上找的一些移植方法，好像一加入了都自动生成网卡设备。
另外，我用的文件系统是FC900自带的，很急，请高手分析 一下。

哪来的 rausb0 ? 不是 wlan0 吗？  怎么用 ifconfig？ 不是 iwconfig ？

先用ifconfig -a看看是否有rausb0或wlan0,然后在用iwconfig进行操作...

谢谢楼上的，问题以解决，之前我认为驱动模块只要一加载上去，就会有网络设备在， usb驱动有点不一样，usb_rtusb_probe（）之后才会有生成网络接口rausb0, ifconifg rausb0 up 后才会显示rausb0的信息

现在产生新问题：我在PC机上，可以一插上usb网卡就能自动识别网卡，ifconfig 可以看到rausb0网卡的信息， 现在我在arm板上，插上usb网卡，只是先探测一下，不能自动识别，用 ifconifg rausb0 up 后才会显示rausb0的信息，别外我现在在/etc/sysconf/.../ifcfg-rausb0 中设定固定IP的信息也没有去读配置，
我想要的结果是，不用ifconfig只要一插入usb网卡就能自动用/etc/sysconf/.../ifcfg-rausb0中的设置去配置。运行，请教了！！！！
