No response, very sad...
Can at least anybody confirm that NO ttyACM device files are created though
CDC_ACM devices are present? Is there anybody else with a CDC_ACM device?

I don't know if that device will work - never tried that. But
udev works perfectly with my mobile phone:
[kay@pim ~]$ ls -la /dev/ttyACM0
crw-rw---- 1 root root 166, 0 May 9 21:57 /dev/ttyACM0
[kay@pim ~]$ tree /sys/class/tty/ttyACM0/
/sys/class/tty/ttyACM0/
|-- dev
`-- device -> ../../../devices/pci0000:00/0000:00:1d.1/usb3/3-1/3-1:1.1

Why does udev have to do anything special for acm devices, they should
work just fine. Do your devices not work properly somehow?
thanks,

Thanks a lot for replying to my latest posting :-)
Every time I want to use the USB Modem for the first time after a system
(re)boot I have to do
mknod /dev/ttyACM0 c 166 0
manually to get the device file though
/sys/class/tty/ttyACM0/ is present
root@localhost ~]# ls -l /sys/class/tty/ttyACM0/
total 0
-r--r--r-- 1 root root 4096 May 12 13:33 dev
lrwxrwxrwx 1 root root 0 May 12 13:33 device
-> ../../../devices/pci0000:00/0000:00:10.1/usb2/2-1/2-1.1/2-1.1:2.0
lrwxrwxrwx 1 root root 0 May 12 14:05 driver
-> ../../../bus/usb/drivers/cdc_acm
[root@localhost ~]#
[root@localhost ~]# cat /sys/class/tty/ttyACM0/dev
166:0
[root@localhost ~]#

Does running:
/sbin/udevstart
create the node for you?
