Hello,
I want to use my old HP P1005 printer as CUPS network printer. I was able to passtrough device to LXC container and everything was working fine using this additonal lines in config:
The problem is that the printer stopped to work after restart. I looked into host and I noticed, that this time printer was not under /dev/bus/usb/004/006, but /dev/bus/usb/004/002.
I wanted to use udev to create symlink, but it didn't worked (hp-setup was not able to find printer).
So I was trying to use:
but this didn't worked. After changing to
it finally started working.
Can someone explain it to me, why those paths have to be the same on host and guest? I was thinking, that path on guest can be different than on host. Second question - why it was not working with symlink? I expect, that this will be something similar, but first I'd like to understand, why names on host and quest have to be the same.
Tested on PVE 7.0-11.
