Wifi adapter

I went and picked one of these up at Fry's since they were $10.
Using usb passthrough from my fedora host to the ubuntu vm, I
can get the device to come up with either the r8188eu driver that
comes with Ubuntu, or the 8188eu driver that tp-link provides.

One thing I had to do when rebooting the vm was remove and reinsert
the device, but that could just be an issue with using it through
usb passthrough.

This is with 14.04.3 running 3.19.0-25-generic

Perhaps if you want to use the tp-link provided one, maybe blacklist
the Ubuntu driver.
