Hello, thanks for the response. My rule is in "55-my-rules.rules"
For SUBSYSTEM=="tty" the usb_id is called in 60-serial.rules.
I also tried it with "ATTRS{bInterfaceNumber}" instead of the "ENV{ID_USB_INTERFACE_NUM} ", but also no success. Regards Daniel Am 09.10.2024 um 15:59 schrieb Mantas Mikulėnas:Did you place your rules in the correct order? ENV{ID_USB_INTERFACE_NUM} is set by usb_id in 50-udev-default.rules,
Only for SUBSYSTEM=="usb"
so it would be available in 60-foo.rules but not in 20-foo.

Therefore I create the following udev rule: SUBSYSTEM=="tty", KERNEL=="ttyACM[0-9]*", ENV{ID_USB_INTERFACE_NUM}=="02", ATTRS{idVendor}=="1dfb", ATTRS{idProduct}=="0010", SYMLINK+="2a" But a "udevadm test /sys/class/tty/ttyACM1" shows, that there is no match, a symlink is not created. If I remofe the "ENV" pattern, the rule is working. Any idea, whats wrong here?
