Looking at the PR6000LCD... entry, it looks like PR*LCD models might be different than the older PR* ones.

What do you get from "sudo usbconfig dump_device_desc"? (You can trim any non-UPS data - I'm mostly interested in idVendor and idProduct. Also, if you don't want to share the full serial number, it would be good to know how many characters there are.)

I suspect this UPS will work with the usbhid-ups driver, or if not, it can be made to work with minor NUT configuration changes. I forget how you choose a "generic" USB connection in FreeNAS - maybe someone else can chime in on that point?

^ This command probably indicates that the NUT driver failed to start, so the NUT upsd process probably will not start, either.

^ upsmon "Connection refused" errors (on FreeNAS, or other connections to localhost) are usually a consequence of upsd not starting, so this should resolve itself once you can get the driver running.

However, as soon as I try to establish a connection between FreeNAS and Cyberpower PR2200, I receive these error messages. I spent many hours in reconfiguring and trying new/different ports, however, it looks like I’m going in the wrong direction, because I can’t get this battery communicating with FreeNAS correctly.

I doubt this will be an issue here, but I would recommend choosing the port you want to ultimately use (serial, USB, network) and making sure that it still works with Cyberpower's software before switching to NUT. Some older UPSes (and likely not even from Cyberpower) did not deal well with switching between ports, and required a power cycle to switch.

for reference, I think this version of FreeNAS includes NUT 2.7.4.

If this works with a different driver, would you please send a snapshot of the information you get from upsc, upscmd and upsrw as mentioned here? http://networkupstools.org/stable-hcl.html#footnotes

Thanks!
