原因未加载USB驱动

5.1 加载usbcore.ko
insmod /lib/modules/2.6.14-hi3511v100dmeb-release/kernel/drivers/usb/core/usbcore.ko

显示
usbcore: registered new driver usbfs
usbcore: registered new driver hub
加载成功

5.2.1 如果为USB1.1 加载hi3511_usb_1-1.ko

insmod /lib/modules/2.6.14-hi3511v100dmeb-release/misc/hi3511_usb_1-1.ko

显示

5.2.2 如果为USB2.0 加载hiusb.ko

insmod /lib/modules/2.6.14-hi3511v100dmeb-release/misc/hiusb.ko

显示

加载成功

5.3 然后再加载rt3070sta.ko
insmod /xxx/rt3070sta.ko
显示
rtusb init rt2870 --->

#ifconfig -a 可以查看到ra0设备的存在

若无密码或密码为WEP加密，则此时可以启动无线, 若密码为WPA加密,则需移植wpa_supplicant,往后再说移植

6.无密码或密码为WEP加密:
6.1 启动无线

启动成功

6.2 设置ip
#ifconfig ra0 192.168.1.230 netmask 255.255.255.0

6.3 扫描无线网络
#iwlist ra0 scan

显示以上信息说明模块已经正常工作

6.4 设置SSID和WEP加密算法
可以参考里面的iwpriv_usage.txt进行配置，

6.4.1 无密码
Config STA to link with AP which is OPEN/NONE(Authentication/Encryption)
1. iwpriv ra0 set NetworkType=Infra
2. iwpriv ra0 set AuthMode=OPEN
3. iwpriv ra0 set EncrypType=NONE
4. iwpriv ra0 set SSID="AP's SSID"
