The fix:

Delete AppleHPET.kext from /System/Library/Extensions

USB is flying and my systems sleeps and shuts down!

Quick and dirty:
Using Finder, copy the Kext to the desktop or somewhere as a backup (or you can use OSX86Tools too). Better be safe than sorry!
sudo rm -r /System/Library/Extensions/AppleHPET.kext
