Why do my USB devices turn off when not in use?

[cerescornnotes]

If I'm watching a video or chatting with friends and my keyboard and mouse are inactive Windows turns off all my USB devices and then turns them back on a few seconds later.
I've checked many websites that address this issue and followed their recommendations, but nothing worked. This problem is really frustrating, especially since i don't know anyone else who has experienced it and I haven't found a solution online.
Please help!

Do that with every controller/Hub.

Your USB devices might be turning off due to powar-saving settings. Try this: open Device Manager, find USB Root Hub, right-click, go to Properties, and uncheck “Allow the computer to turn off this device to save power” under power Management. Also, disable USB selective suspend in your power plan settings. Should fix it!
