USB+device+failure

If a USB device fails i.e:-
 * The Web cam freezes or there is no image
 * The USB I/O screen does not respond to commands
 * The CCD camera fails to respond

This is probably due to a USB device failure. This has happened on occassion due to electrical surges etc.

To try and resolve the problem follow the procedure below:-


 * First........CLOSE DOWN** the following software:-
 * The Web cam
 * The Observatory Auxiliary Control screen (no need to disconnect)

Then, Goto Start>Control panel>System

Make sure you are in the 'Hardware' tab. Then click on 'Device Manager'

Scroll down to 'Universal Serial Bus controllers' and click ONCE to highlight it

The on the top menu bar of of the Device Manager screen, cick 'Action' and then click 'Scan for hardware changes'. This should resolve the USB connection issue. The appropriate software (Web cam, USB I/O etc) should be restarted.
