Hi all, at the moment I’m trying to attach a 4G LTE modem to an unprivileged LXD container. This device is a cdc-ether device that creates a usb0 interface to which it provides a local IP address acting as a DHCP server.

I would like to isolate this device from the host, by having the USB processes that lead to the usb0 interface being created completely happen in the container. Is something like this possible? This is not a libusb device (so the usb device type doesn’t work) and isn’t a block character device either.
