[Nut-upsuser] NUT Quit Working

	I have had NUT working for several years on my servers.  Recently I 
made changes to the main server, where the UPS is local, and now upsd 
won't properly load there, which essentially disables the entire UPS 
shutdown system.  I made a number of hardware and software changes, 
including an upgrade to the latest software versions for that distro 
(Debian Wheezy), although I did not upgrade to a new distro, and I did 
not make any changes that should affect the UPS, unless NUT was one of 
the packages automatically upgraded.  No changes were made to the UPS 
hardware or the NUT configuration files.  When upsdrvctl runs, I get the 

RAID-Server:/RAID/Server-Main/Equipment/HighPoint Adapters# upsdrvctl start
Network UPS Tools - UPS driver controller 2.6.4
Network UPS Tools - Tripp Lite OMNIVS / SMARTPRO driver 0.20 (2.6.4)
Warning: This is an experimental driver.
Some features may not function correctly.

Detected a UPS: unknown/unknown
libusb_set_report() returned 0 instead of 8
Error reading protocol
Driver failed to start (exit status=1)
