 From which version did you upgrade it?

The driver isn't running, so the problem isn't in the server.

See above.

It should be created by the driver, which apparently isn't running.  
Either it isn't started at all, fails to detect the UPS or isn't  
running with the proper permissions.

Please post the output of

     /path/to/megatec -a mustek -DDDDD

here and I'll take a look.

Best regards, Arjen
