Should note that the registry key for controlling the enhanced power management may not be present once you locate your device ID in the registry. You can right-click and create it as a new DWORD (32).

This can solve some very strange issues with your USB ports. Aside from being the fix for my PS3 knock-off controller, it also resolved that annoying crap where my USB3.0 hard drives would go into standby and would fall back to USB2.0 mode when they woke up. Didn't happen with the thumb drives, only the big 1TB hard drive I used for the full backups. Makes a big difference when you're dealing with 20+GB backups.
