USB device ID is chaning every other second?

[kriznik]

Hello there,
it will probably be HW related I guess, but worth to try to ask
I have CyberPower UPS connected via USB to the Proxmox Host and I'd like to have NUT running.

But i noticed, that device ID is changing basically constantly whenever I run lsusb, therefore it would not be possible to pass it to the lxc right?
Is that behaviour which is expected, or something wrong with my (new) UPS?

just example, ID 59 then missing, then ID 60 and so on

But i noticed, that device ID is changing basically constantly whenever I run lsusb, therefore it would not be possible to pass it to the lxc right?
Is that behaviour which is expected, or something wrong with my (new) UPS?

Looks like it's disconnecting and reconnecting continuously. Check journalctl (scroll with the arrow keys) for more information about why. It could be an incompatibility between your USB controller and the UPS. Try another port (connected to another USB chip) or try putting a (powered, yes, I see the irony) USB hub in between. Search the internet for incompatibilities between Linux and your UPS (as this is most likely not a Proxmox specific issue).
