Somehow reading the report descriptor fails, either due to a problem  
in the UPS or in the libusb library (assuming you ran the above  
command as root and no other application was using the UPS at the  
time). I have no idea how to locate which one is the culprit, let  
alone find a way to work around this. Unless you can make the above  
command work, there is no way to support this device in NUT.
