Yes.I can change usb port/board in 5 minutes.Look at the you tube video that is posted in my motherboard thread.Also read 2 threads by duguet and keithharris about usb replacement.
You dont need to take out mb, just take out the mb screw closest to usb board to get room to pull out usb boards cable.The cable under the mb is stuck down with tape.

And you shouldnt need a new mb, someone is talking crap.
