Chances are, you have a spare XBox controller cable lying around (in my case, from making StepMania dance mats) and a female USB connector, soldered in some useless piece of electronics. With those parts it is child's play to make an adapter.
These adapters are simple and common builds, however, they often end up looking terrible, and taking up room. My version is small, sleek, and doesn't require modifying XBox hardware.
Step 1: Gather Materials
-XBox Controller cable or extension
-Junk USB Female connector
-Hot Glue gun
once you've got these, the fun can start.
