USB Passthrough for LXC

The best way I found is to map the specfic USB by-id through to the LXC directly.

So, in the LXC config something like:

dev0: /dev/serial/by-id/usb-0658_0200-if00

This can also be achieved from the UI by selecting the LXC then going to the resources tab and add, then select passthrough and type in the ID.

The USB will be deterministically mapped to the LXC and is available in /dev/serial/by-id/<device id>
