The suggestion to use SUBSYSTEM="tty" works for me on my system.

In my testing, SUBSYSTEM=="tty" seems to be the right set of udev runes.

Not thorougly tested, but seems to work.

IMO this is only a workaround, as most suggested to create symlinks to usb-devices with serialnr. is:

Code: Select all

SUBSYSTEMS=="usb", ATTRS{serial}=="12345678", SYMLINK+="MyUSBDevice"
Solution from XECDesign: https://github.com/raspberrypi/linux/is ... -755231352

Udev rule has to look like:

Code: Select all

SUBSYSTEM=="tty", ATTRS{serial}=="12345678", SYMLINK+="MyUSBDevice"
