It seems you are right, if I plug in the USB cable from the case I get USB devices has malfunctioned and windows does not recognize it. Another thing occur today: I want to transfer some video files from my panasonic sd99 camcoder connected to usb2 back port, the camcoder wasn't recognized then the driver talent found Mats***a sd99/sd usb device but after install driver nothing happens - no new drive icon or autoplay function.
I don't know what is going on but until I have this Gigabyte mobo problems occurs one after another, I will join hafexo from another post and also never buy a gigabyte product again !!
