Note that I'm not convinced that reading until a timeout is received  
is a good idea at all. So maybe we should just create a separate  
subdriver here and allow people to override the build in automatic  
subdriver selection (which is possible for blazer_usb).

As for the OP's problem, I'm not convinced that your patch would work.  
This could also very well be a problem with the UPS not understanding  
that we want to read the rating (and locking up afterwards). So unless  
we get a reply on this question, I don't think making any  
modifications at all would be a good idea.

After all, it looks like the OP also tried the megatec_usb which  
didn't work either, although this one does read until timeout (so this  
probably isn't the problem here).

Best regards, Arjen
