The sad news is that the XBOX 360 Wireless Controller for Windows driver does not currently work after sleep/hibernate.
I wrote a small platypus script that unloads/reloads the kext. Show contents and look in resources/script for the actual shell script commands.
You may need to recreate the app using platypus, as it requires admin privileges?!
If anyone smarter than me could use this shell scrip in a wake script to totally automate the process, that would be great. As it stands, I just create a shortcut to this app on the desktop, and run it when I need my 360 controller back
It takes 5 to 10 seconds to work in the background (with no feedback), so be patient.
Tested on Mac OS X 10.9.2 on a Core i5 hackintosh.
App is attached, and also available here:
