WARNING!
If anyone has a PC wireless adaptor for the Xbox 360 controller, DO NOT plug it into your tablet. The adaptor pulls too much amperage and may damage your hardware.
There's a common defect on these that causes the internal (SMD) fuse to blow because it's pulling too much current.
I fixed mine by simply soldering a bridge across the fuse, since my motherboard's USB ports can supply 1500 mA, three times the spec, I'm not too worried about it causing problems.
The wired connection is worth trying, and shouldn't cause any damage, but I just wanted to warn anyone who might have a wireless lying around they had an urge to try.
