[Nut-upsdev] Liebert PSI 1440 support

[Peter Selinger]

This looks like a libusb issue to me, not a NUT issue. Perhaps you
should write to one of the libusb mailing lists:

http://sourceforge.net/mail/?group_id=1674

Once you manage to connect to your device, please report back and we
can continue from there. -- Peter
