Reply to MIDI Fighter Classic - Hardware Issue

My trusty MIDI fighter classic seems to be dying a slow painful death and I would like to know if any of you have any ideas about how I can repair it and if the parts are out there for me to fix it.

The issue is the USB port. When I touch the USB cable ever so slightly, it disconnects briefly and restarts the MIDI fighter. The port is now becoming so sensitive, that if I hit one of the buttons too hard or really get in to a combo, it will vibrate it enough to cause a disconnection.

So really what I'm wondering is if I can replace or repair the USB port on it, or if I have to get a new motherboard for it?
