Did a bit of Googling on this and it looks like you're not alone, although it's almost certainly not Skyrim that's the problem - people experiencing the same problem mention a variety of games. Seems there's no easy answer. Microsoft just people to redownload the drivers and then contact support if that doesn't work. You've already done that, I guess.

So, it's "process of elimination" time. If it's not Skyrim then it's either your controller or your PC. Something is causing the USB device (the controller) to disconnect. The obvious thing to do is try a different Xbox 360 controller, to settle for sure whether it's the controller or the PC.

It's more likely to be the controller. Check it's physically OK, Shake it and see if it disconnects. Waggle the connecting cable to check for loose wiring, dirty connectors, etc - basically anything that could cause a momentary disconnect, making your PC (and therefore the game) think the controller has been unplugged.

Some people mentioned a failing controller battery pack causing it for them, or accidentally hitting the pairing button during gameplay, but those are wireless controller issues and you said yours was wired. There's no battery pack or pairing button on my wired Xbox 360 controller.

If it's the PC, then it's going to be a device driver problem, a problem with your USB hub, fluctuations in the power supply to the USB device, or just plain old dirt in the USB port. Try connecting some other USB devices that draw power from the USB port, e.g. a digital camera, and see if it shuts itself off.

You're just going to have to eliminate the possibilities one by one to locate the problem.
