Hi Mark,
Try resetting all USB devices.
To do this open Device Manager and expand Universal Serial Bus controllers. Delete all in the tree and then shut down. Disconnect the power supply, remove the battery and then hold down the power button for 30 seconds.
Re-attach the power adaptor, reconnect the battery and re-boot - Windows will reload all USB drivers.
Does anything then appear in Device Manager? If not you could have a hardware problem.
