Do you have link to your motherboard manual? Im try find it cuz wondering about something.... anways linkage please.
Did you check to see if the jumper was placed on correctly?
Yes i found the manual. It should reconize it, and if i remember correctly it should auto install the drivers needed cuz it would copy out your drivers for the first two usb ports that are already attached.
Double check the orentation of the jumper on the USB1 jumper
