I have Lemaker Guitar board with Debian 8 based OS on it. The board has two network interfaces - ethernet and on-board WiFi chip. I need to use third interface - USB WiFi card. lsusb returns:

Bus 001 Device 002: ID 148f:7601 Ralink Technology, Corp.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

The first line is my USB WiFi card so drivers are properly installed because system recognizes it right? But I don't see it in ifconfig -a:

eth0 and wlan0 are the two interfaces built in the Lemaker Guitar board. Not really sure what are ip6tn10 and sit0 interfaces, but since they have no HW address I assume they are not my USB WiFi card (plus they remain there when I unplug it). So I guess my question is, how do I make it work? How to tell my system that Bus 001 Device 002: ID 148f:7601 Ralink Technology, Corp. is a network interface?

Ok I got it working. Copy paste from Lemaker forum:

copy the provided .ko file to /lib/modules/3.4.xxx/kernel/drivers/net/wireless/
then run "sudo depmod -a" from a terminal
then run "sudo modprobe -f mt7601Usta"

and I downloaded the .ko file http://mirror.lemaker.org/MT7601.tgz

  • And the way to debug it is to look into dmesg. There you would have seen that even though lsusb "recognizes it" (i.e. the USB device gets enumerated), it doesn't load a driver for it. Also, you shouldn't need modprobe the next time once you've run depmod, the kernel module should load automatically (if it's correctly written).
