I am curious about why the Interrupt Out packet is sent by the Windows software
if it isn't to turn off the UPS. Is it possible to do some more testing with
shorter timeouts so that the battery doesn't get depleted? You would need to
record the exact time when it shuts down, I think.

Also, I quickly put together a man page:

Let me know if I should add anything.

Sure, I will do the test during the weekend.
I'm not sure if it's related, but, using the driver these days I noted
that I sometimes the connection to the ups drops and resets, like this,
while I hear the click sound of a relay:

Looks fine to me.

If it's not too late for your tests, I committed a v0.03 to the
'atcl' branch, with string matching to avoid confusion with other
0001:0000 devices.

We've definitely heard of cases where an UPS will generate enough noise on
the USB bus that it disconnects. The best we can do is try to re-attach to the
same device when it comes back. The current driver should handle this - if not,
please send debug output from the driver. (Probably at least -DDD)
