tencent USB wifi (MT7601) cannot be found in ubuntu14.04.1

I use tencent USB wifi (MT7601), and follow the driver install instructions:

sudo apt-get install git
git clone https://github.com/porjo/mt7601.git 
cd mt7601/src
make
sudo make install
sudo mkdir -p /etc/Wireless/RT2870STA/
sudo cp RT2870STA.dat /etc/Wireless/RT2870STA/
sudo modprobe mt7601Usta

On my atom ubuntu 14.04.1 LTS, it works fine.
On my BBB board, my OS version:

Ubuntu 14.04.1 LTS \n \l

rcn-ee.net console Ubuntu Image 2015-01-06

Support/FAQ: http://elinux.org/BeagleBoardUbuntu

got from

wget [https://rcn-ee.net/rootfs/2015-01-06/flasher/BBB-eMMC-flasher-ubuntu-14.04.1-console-armhf-2015-01-06-2gb.img.xz](https://rcn-ee.net/rootfs/2015-01-06/flasher/BBB-eMMC-flasher-ubuntu-14.04.1-console-armhf-2015-01-06-2gb.img.xz)

I followed the same instruction and can find “mt7601Usta” using “lsmod”
With “lsusb”, I can find the USB wifi

Bus 001 Device 003: ID 2a5f:1000

no device name followed (same as my PC).

When I use “ifconfig -a”, I cannot find wlan or other relative network adapter.

I don’t know how to debug this issue, can someone help me?
Thanks.

My board is beaglebone black rev C
