To all,

I upgraded my OS from Windows 7 Ultimate to Windows 8 Professional. I realized that a day after installing this, my USB Root Hubs became damaged. I tried uninstalling and reinstalling them but to no look. I searched for Upper and Lower Filter registry keys but couldn't find them. I don't know what to do to fix them.

A separate (but maybe not) issue is that my official Microsoft Xbox 360 wireless controller and my SeaGate GoFlex 3.0 TB External Hard Drive aren't compatible with Windows 8 Professional yet and was wondering if anybody had any workarounds or solutions. The external hard drive worked for the first day of using Windows 8 but after shutting it down one night and turning it on again the next day, it stopped working with the OS. I used System Restore but that didn't do anything either.

Please help me if possible. Thanks guys.
