The USB on the computer is communicating with the MIDISPORT so it's not the USB port itself.You've tested cables so it's not those.Can only be 1 of 2 things:
1. Driver for the keyboard
2. USB on the keyboard.
Go to the site for the keyboard and DL a new driver. If that doesn't work get the keyboard to the shop.
