rt3070ap: Unknown symbol rausb_buffer_free

1)  另外需要修改的地方

NETIF/os/linux/usb_main_dev.c中添加MODULE_LICENSE("GPL");
MODULE/common/rtmp_init.c中的MODULE_LICENSE("RALINK");改为MODULE_LICENSE("GPL");

否则会出现
[ 1011.612979] rt3070ap: Unknown symbol rausb_buffer_free
[ 1011.613153] rt3070ap: Unknown symbol RtmpOSTaskNotifyToExit

2) 拷贝出来

cp  MODULE/os/linux/rt3070ap.ko /tftpboot
cp  NETIF/os/linux/rtnet3070ap.ko /tftpboot
cp  UTIL/os/linux/rtutil3070ap.ko /tftpboot

3)按顺序加载
#insmod rtutil3070ap.ko
#insmod rt3070ap.ko
#insmod rtnet3070ap.ko
4）dmesg
[165621.092955] rtusb init --->
[165621.256473] usbcore: registered new interface driver rt2870

5)这时插入rt3070，然后dmesg
