It can take about that long to read the descriptors. The non-Windows NUT drivers will print that message, then return to the command line when they go into the background (seems similar to your case, if I understand that you ran the PowerShell process list command after that 45-second wait).

Speaking of which, what version of NUT is this? Given the exact version string, those without Windows systems can at least look at the source code. I know there are some differences in the logging, but I don't recall the specifics.

Here's the NUT stack:

UPS <-> Driver (usbhid-ups) <-> Server (upsd) <-> Clients (upsmon, upsc)

I think you have that first link working (assuming usbhid-ups is still running). If the server is not running, you can try starting it manually with one or more "-D" flags to see what is going wrong.

On the other hand, if the driver is only running for that 45 second interval, you can also run the driver manually with "-D". ("upsdrvctl start" is primarily a shortcut for systems that stash the drivers out of $PATH, and also to start multiple drivers in sequence.)
