Paperless-ngx LXC Container with USB Scanner

[sebastianhaeringer]

Hello everyone, I'm new to the Proxmox world.
I'm currently passing my USB scanner to my Paperless LXC as a "device passthrough" via the Proxmox GUI – and it works great.

However, if I turn the scanner off/on or dis-/connect the USB connection, the USB bus ID changes and the scanner is no longer recognized by the LXC. I then have to find out the new USB ID and pass it to the LXC again.

Is there a dynamic way to do this? I would like to turn off my scanner, as it draws a lot of power in standby mode.

With my zigbee2mqtt LXC I didn't have to pass the sonoff usb dongle on and could access it directly?
