[Nut-upsuser] NUT 2.8.1-3 " Can't claim USB device [051d:0002]@0/0: Entity not found" using usbhid-ups
Hello, I was thinking about what could be going wrong here, and a few ideas pop up: 1) If you installed NUT from packaging, there should have been no need to add OS groups/users manually. There is a valid use-case for running different daemons under different accounts, as long as they talk over network and access same files or UNIX sockets at best by sharing a group for that, but it does need some careful planning to pull off :) In the worst case, if you also "chown"ed something to these new accounts, and if no daemon actually runs as those, you've locked out the daemons from some access. 2) Access to USB device filesystem nodes should be governed with udev on that platform, check if you have a file like /usr/lib/udev/rules.d/62-nut-usbups.rules and if it lists USB IDs of your device 051d:0002 3) Driver options bus, device, busport can depend on topology and enumeration of connected devices; it may be wise to comment them away. Later NUT versions already do not default to offering them in `nut-scanner` output, to minimize run-time surprises. 4) See if you already have a service instance `nut-driver at apcupskelder.service` defined and running, since NUT v2.8.0 https://github.com/networkupstools/nut/wiki/nut%E2%80%90driver%E2%80%90enumerator-(NDE) could have created it - but the older blogs/videos do not reflect this facility. The "terminating other driver" seems to be a clue in that direction. Maybe that other copy of the driver is what holds the USB port. Also avoid `upsdrvctl` in that case. Notably, if the driver already runs under that service, and `upsd apcupskelder` returns data - maybe you don't have to do anything. There might be some other loose threads to pull, but please check these ones first as most likely :) Jim On Wed, Oct 30, 2024 at 11:58?AM Erik De Boeck via Nut-upsuser < nut-upsuser at alioth-lists.debian.net> wrote:> Hi all, > > Yesterday, I bought a UPS for the first time in my life, and was eager to > dive into NUT.

[Nut-upsuser] NUT 2.8.1-3 " Can't claim USB device [051d:0002]@0/0: Entity not found" using usbhid-ups
Hi Jim,
Thanks for your help. I'll respond in the same order as you did:
1. Unfortunately, I did "chown" stuff to these created users...
Since
the other three responses don't seem to be what you're looking for
(but
that's only my uninformed interpretation), I suppose the problem lies
here?
Is there a number of files/directories that I should "chown" again
with
user "nut"?
2. ```

3. I believe I commented these away? Are you suggesting I change
something?
