Description:   Opened: 2008-02-02 13:23 0000 
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.
