This device cannot start. (Code 10)

I plug in the device and everything shows up properly.iTunes opens but will not recognize the device.In Device Manager the Apple Mobile Device USB Driver shows nothing wrong.Now here is the problem: as soon as I press Trust on the iPod Touch 5 the Apple Mobile Device USB Driver shows a yellow triangle with a black question mark in it.When I click properties it shows this error:

This device cannot start. (Code 10)

I've tried reinstalling iTunes, removing the drivers then reinstalling them, restarting the iPod, erasing all data and settings.At one point, the PC recognized the iPod as a Portable Deivce but iTunes didn't recognize it.What can I do?
