I'm using your VIA chipset motherboard P3TDDE, and I noticed that the motherboard has 2 USB ports on the back and 2 connectors on PCB but when I finished install Window 2000; it shows 5 USB ports. Where is the fifth USB port on the motherboard?
The fifth USB port is for the build in ACR slot. You need to get an ACR USB card in order to take advantage of the fifth USB port.
