Have you also tried the newmge-ups driver? Being based on the same  
core as the usbhid-ups (USB) driver, it may be a little more forgiving  
in case of timeouts (although I'm not very familiar with it's  
predecessor, mge-shut).

The SHUT protocol is *very* verbose and uses a slow 2400 baud link, so  
you want to give it lots of time before giving up (reading a 1500+  
bytes report descriptor will take more than 10 seconds). You may want  
to increase MAXAGE in upsd.conf to at least double that, to prevent  
PINGing the driver to death.

Best regards, Arjen
