This usually means that more than one driver is active for the same  
USB device and/or hotplug/udev isn´t setup properly. It could  
occasionally happen if the connection is lost as well.

This debug level is too low to provide enough input. For this problem,  
you'll need to run it with debug level 5 before it will show what is  
going on. Please note the following from 'man 8 nutupsdrv':

"The level of debugging needed depends both on the driver and the
problem you're trying to diagnose.  Therefore, first explain the problem you
have with a driver to a developer/maintainer, before sending them debugging
output.  More often than not, if you just pick a level, the output may be
either too limited or too verbose to be of any use."

Best regards, Arjen
