I've used openSUSE 11.2 in the past too (using 11.3 now) and have  
never seen such a problem with any of the USB connected UPS'es I  
tried, so this pretty much rules out a libusb issue. It must be  
vendor/device specific, probably the reason why the developers don't  
see this. Since we're not able to do anything with reports that are  
*longer* than expected anyway, we can safely assume that anything in  
excess of the number of bytes that we calculated from the report  
descriptor can be discarded. Therefor I have restored the nut-2.4.1  
behavior of only reading the number of bytes expected.

Thanks for reporting this.

Best regards, Arjen
