DRIVER_POWER_STATE_FAILURE on shutdown
We've got this problem with some HP desktops that, from time to time, won't detect anything connected to the USB ports. It's very confusing, because it happens in a apparent random fashion. The machines are brand new HP ProDesk 600 TWR.
I feel it's a driver problem, and my mates think the trouble comes from cloning. The supplier thinks the problem comes from the special POS keyboards we use.
Anyway, the fact is that, when it happens, you can't press CTRL+ALT+DEL to enter Windows, as one of the non detected hard is the keyboard, so we press the button to turn the computer off, and it takes ages until decides to BSOD with a DRIVER_POWER_STATE_FAILURE.
Any ideas?
