Intel DQ87PG Mainboard with WIn7 Pro x64 restarts some seconds after shutdown when HP Laserjet P2015 Printer is connected to any USB port and the Printer is powered on. When i power off the Printer before shutdown, the mobo powers off after shutdown. This behaviour is reproducable on all DQ67PG Boards i tried(5 Boards).
Switching the USB Port where the Printer is connected does not resolve this behaviour.
Any hints?
