Hi all, I'm going to be using a number of the Korlan/8devices usb2can interfaces and I want to make sure they have persistent interface names. Thankfully they all have unique serial numbers that are printed on the devices so I can match a physical device with a linux interface name. In theory I should be able to do something like add a file at /etc/udev/rules.d/10-usb2can.rules containing something like: SUBSYSTEM=="net", ACTION=="add", ATTR{ID_VENDOR_ENC}=="8Devices", ATTR{ID_MODEL}=="USB2CAN_converter", NAME="can$attr{ID_SERIAL_SHORT}" But I've not been able to get anything to work. Has anyone been able to get something like this to work? I'm on Debian Buster.
