Broken USB port on Melzi

Hi All

Due to extreme clumsiness I managed to pull the usb connection off my Melzi board, is it possible to replace it? The wires have snapped where they meet the board, is it possible to buy a new usb connector (I'm assuming I need to remove the wires that run into the board). I'm happy to post pictures if this helps. I'm guessing I'm not the only person this has happened to, I think an easy way to stop this happening is to tie the usb wire round the frame of the printer or even print a special connector.

If the answer is no is it possible to set up a bluetooth module without usb access? Is it possible to update the firmware without usb access?

Thanks
