Hello,
Have you installed your chipset drivers for you new motherboard? Your motherboard should come supplied with a CD containing drivers for components on your motherboard.
Check to see if drivers have been installed for your USB ports at
Control Panel >
System >
Hardware Tab >
Device Manager...
If you don't have a driver CD and drivers aren't installed, you can download them at ASUSTeK's website:
