[Nut-upsuser] usbhid-ups becomes unresponsive after extended period

So just to clarify - the faulty system uses the older packaged NUT (in
Linux) and the newer build of master (in FreeBSD) works better?
Does the newer one also use libusb-1.0 dependency (vs. 0.1 likely for
packaged one), is the custom build that new? It may be that some transport
deficiencies were fixed in that, or in NUT over the years.
For that older setup, probably there are some timeout settings to tell the
driver to reconnect somehow, but can't remember ATM. Also different systems
varied with success of active polling vs interrupt delivery, so "pollonly"
(and freq) options can help.
