that may be part of the issue... long time I've not tried the 2.x series,
not sure how it goes nowadays.
btw, any interesting "usb" messages from your syslog?
also, would you be able to test with a 3.x or 4.x, at least to see if that
improves / solves the issue?

don't bother too much, in the end, such request only get an answer once it
has reached me ;)

that requires the driver to be running, then it's published as ups.firmware.
as per my upsc output above (in my case): ups.firmware: 02.06.0019
