[Nut-upsuser] Fwd: Data stale error after short while

> Hope this helps.

It did - thanks! I managed to hack around a bit earlier and did produce the
driver binary but thought I would try from fresh with your steps and got
the binary.

Unfortunately the problem is still there... after a while connection is
lost, updates stop, and upsc reports stale data. Log attached.

What I'm thinking now is that I should run a cron job that regularly (every
5 minutes?) restarts the driver. Just killing and restarting nutdrv_qx
doesn't work though, since the new process fails with unsupported device
errors. Ideally what I need is for the USB driver to reattach itself in the
cron and I think that would probably work. It's a hack, but should probably
work. No idea where to start on this though. Let me know if you think I'm
barking up the wrong tree.

Something that puzzles me - when I restart the driver after a disconnect,
this is a typical output from the driver with -DDDDD log level. It clearly
can see, but not communicate with, the UPS. I've pasted it inline rather
than gzipped it because it's short output. Hope that's ok within the forum.
