这篇文章说得其实很好了，在Linux下使用“360随身WiFi 2”：http://www.linuxdiyf.com/linux/14648.html
不过因为专利问题，官网貌似不直接提供驱动下载了。不过在Ubuntu下有个PPA已经添加了这个驱动：
sudo add-apt-repository ppa:thopiekar/mt7601
sudo apt-get update
sudo apt-get install mt7601-sta-dkms
然后都不需要重启就可以搜索到wifi了。
There is a PPA repo available containing a DKMS-capable package based on this repo:
https://code.launchpad.net/~thopiekar/+archive/ubuntu/mt7601
And the source code is here
