得到 vntwusb.ko

编译成功vntwusb.ko
root@ss-desktop:/camera/workdir/VT6656_Linux_src_v1.20.05_x86/driver#
file vntwusb.ko 
vntwusb.ko: ELF 32-bit LSB relocatable, ARM, version 1 (SYSV), not stripped

增加内核支持wifi的ko文件：

Device Drivers --> Network device support -->Wireless LAN (non-hamradio) --> Wirwless LAN drivers

  │ │[*] Wireless LAN drivers (non-hamradio) & Wireless Extensions        │ │  

如果不增加内核支持会出现：
# insmod vntwusb_arm120.ko
insmod: cannot insert `vntwusb_arm120.ko': Unknown symbol in module (-1): No
such file or directory
增加内核支持后：
insmod vntwusb.ko
dmesg可显示：

ng Wireless LAN USB Driver 1.20.05

可以insmod上，没问题。

但是，当插入WIFI时显示：

dmesg里显示：

可能是USBHOST支持的不是很好。问题在查。
