cannot read device status, Protocol error (71)
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.
Best regards, Arjen
