Indeed. We now try to reconnect if we received an unexpected error and
this is something that leads to termination of the driver during the
initialization phase. I suspect that the report descriptor (see my
previous message) might help us find out where this error originates from.
I suspect that the report descriptor in the UPS is lying to us and
mentions a variable that really isn't available.

If you want to try a quick fix, in 'drivers/usbhid-ups.c' change line 1283
1281 /* Don't know what happened, try again later... */
1282 upslog_with_errno(LOG_DEBUG, "HIDGetDataValue");
1283 return FALSE;
This will make the driver continue as usual for this unexpected error, in
the hope that it will go away eventually. If not, it will keep logging
this error every 30 seconds, so that will probably nag people enough to
complain to the mailinglist and we can fix it.
