[Nut-upsuser] usbhid-ups looping and unresponsive after update

Running the driver in debug mode has always prevented it from
backgrounding, so nut-2.2.0 would also require a 'kill -9' to stop it,
unless it would have terminated because of some error condition. If it did
and nut-2.2.1 no longer does, count your marbles, because apparently a
problem that existed before was fixed between these versions. You
shouldn't run any driver in debug mode, unless there is a reason to do so.

There have been massive changes to this driver and if I remember
correctly, more debugging information will be displayed to help us locate
problems with some UPS'es more easily. Anything above debug level 2
('-DD') should only be used when a developer specifically asks for it.

So far you have not convinced me there is an issue with this driver.
Please be more specific in what problem you're trying to solve by running
the driver in debug mode.

Best regards, Arjen
