USB-WIFI-RTL8188F不工作,未见报错

使用USB的wifi模组,型号是RTL8188F,编译驱动后放进去insmod,没有看见报错,有一些信息打出来,但ifconfig wlan0 up,提示ifconfig: SIOCGIFFLAGS: No such device
可能是什么问题?

顺便再问一个:
F1C200S的USB-DP应该接模组的D-还是D+?
我是用飞线试的,线长大概20CM,这个会影响吗?

Re: USB-WIFI-RTL8188F不工作,未见报错

用这个命名  ls /sys/class/net/ 查看一下看看wlan0有没有被命名为其他网卡

$ ls /sys/class/net/
eth0  eth1  lo  sit0  usb0  usb1  wlan1  wlx30eb1f1f3b8f  wwan0  wwan1
    # 出现wlan0和wlan1,其中wlan0被系统重命名为wlx30eb1f1f3b8f
