Cannot forward USB device to Proxmox LXC as it changes ID every time it is unplugged

I am setting up a printer in a Debian LXC image on Proxmox. I identified the printer in lsusb:

Bus 001 Device 007: ID 04f9:01ea Brother Industries, Ltd DCP-7030

and I forward it in Proxmox (device /dev/bus/usb/001/007). As soon as I unplug the printer and plug it back in, it always gets a new ID, for example:

Bus 001 Device 005: ID 04f9:01ea Brother Industries, Ltd DCP-7030

The printer does not show up in /dev/serial/*. There are three possible solutions I can think of: - Somehow fix the ID, such that I can forward it statically - Forward all USB devices - Reference the printer as a symlink (udev rule TTRS{idVendor}=="04f9", ATTRS{idProduct}=="01ea", SYMLINK+="brother_printer" works, but CUPS/SANE are unable to detect it as a printer) I am unsure which of these is the most promising path and how to proceed with it.
