USB Port problem

[Fionn]

Installed MB(not new) into presario notebook 2100 and I have only one problem remaining.USB port will not work/see any items drawing power from the port
but works with my camera ok.I've tried uninstalling the port but to no avail.I'm stumped at this stage.It only has 1 usb port.If I leave a usb mouse in the port(unrecnogised device) and reboot the system hangs.Any ideas pls?[IMG]https://datacave.co.uk/images/smilies/frown.gif[/IMG] [IMG]https://datacave.co.uk/images/smilies/frown.gif[/IMG]

Is the port enabled in the BIOS to recognize the USB mouse?

Sorted- broken pin causing a short.
