Not sure if this is the Motherboard, the drivers or Win 7 issue.
I am using the Gigabyte GA-970A-D3 Motherboard Socket AM3+ AMD 970+SB950 Chipset with the FX 6300 CPU.
When I turn on the computer, my mouse is never recognized until I unplug and replug it in. The same happens for my wireless Cisco Valet. The PS/2 keyboard (not usb) works fine each time, but the USB's only work when I have to plug and play them each time the computer is rebooted. Any ideas?
