Why did you install libusb manually ? Did the installer fail ?

I have just tested here with a 5110 and it works. I guess it is related
to your configuration.

Can you send your configuration files please (nut.conf, upsd.conf,
ups.conf. upsmon.conf and upssched.conf if you use upssched ).

FYI this is the output of upsc for my 5110. I'm afraid it won't satisfy
your needs. Anyway, please send your configuration file since you may
have discovered a bug. :
