我是从官网下载的驱动的,但是我插入设备后打印的信息是:

 [  854.331229] usb 1-1.2: USB disconnect, device number 5

[  857.387702] usb 1-1.2: new high-speed USB device number 7 using musb-hdrc

[  857.498862] usb 1-1.2: New USB device found, idVendor=0bda, idProduct=0179

[  857.514059] usb 1-1.2: Product: 802.11n NIC [  857.518537] usb 1-1.2: Manufacturer: Realtek

 

加载驱动8192cu.ko的驱动时,打印的信息是:

|root@android:/storage/usb1 # insmod 8192cu.ko ifname=wlan0 if2name=p2p0 

[  340.570187] rtl8192cu driver version=v4.0.2_9000.20130911

 [  340.575968] build time: Jul 15 2016 01:16:26 [  340.581004] usbcore: registered new interface driver rtl8192cu

 

感觉驱动根本没找设备,请问下你驱动如何修改的啊?

我驱动只是修改了Makefile文件,其他的没动。
