[Nut-upsuser] USB drivers not found when compiling

[Tyler Montney]

 libusb-1.0-0 and libusb-0.1-4 are installed, cloned the master branch,
same issue.

I think for now I'll just get by with it running localhost. When I
reinstall the packages, nut & nut-client & nut-server, nut-client won't
start.

Mar 24 18:41:19 raspberrypi upsmon[1972]: Fatal error: insufficient power
configured!
Mar 24 18:41:19 raspberrypi upsmon[1972]: Sum of power values........: 0
Mar 24 18:41:19 raspberrypi upsmon[1972]: Minimum value (MINSUPPLIES): 1
Mar 24 18:41:19 raspberrypi upsmon[1972]: Edit your upsmon.conf and change
the values.

I'm not sure what changes between removal and reinstall, all the same
config files remain. I have to change MINSUPPLIES to 0 to get it to work.
The upsc command works and returns values. What is the result of leaving it
at 0? The description explains what it is but not what happens if
misconfigured.
