Just a wild guess, but I guess it doesn't hurt to check the power saving options, both in Device Manager and Windows. If you have some software for that purpose from the device manufacturer, check that too. You don't want Windows shut your USB ports down when not in use, neither to put your computer to sleep mode after 15 minutes. Sometimes it seems that Windows thinks you're not doing anything if everything is buffered to RAM, like watching a Youtube video or even playing a flying sim without using the mouse and keyboard.
