Well I have come across a very strange problem after I started using my powered USB hub today. When I shutdown the computer the CPU fan slows but doesn't completely stop. The only other thing that was getting power was the USB hub, so I unplugged it and sure enough, the fan stopped! I plugged the hub back in and the fan starts up again! If I shutdown the computer and start it back up the computer wont reboot unless I turn it back off, unplug and replug the hub then turn the computer back on. Has anyone heard of this before?
No announcement yet.
USB hub is powering CPU fan.
