When using USB GSM modems (like siemens ES75), the device node which is created is: crw-rw---- 1 root root 166, 0 Feb 2 13:08 /dev/ttyACM0 but other serial ports and modems (like isdn and so on) are made with group of 'uucp'. Can somebody update the /etc/udev/rules.d/50-udev.rules file, where I request the addition of the following line into 'tty devices' section: KERNEL=="ttyACM[0-9]*", NAME="%k", GROUP="uucp", MODE="0660" Thank you. Reproducible: Always
udev-122-r1 does now contain a similar rule.
