A regra do udev que escrevi para o modem CDMA é
SUBSYSTEM=="tty", ATTRS{bInterfaceNumber}=="00", ATTRS{bNumEndpoints}=="03", ATTRS{product}=="ZTE CDMA Tech", ACTION=="add", SYMLINK+="CDMAModem"
e
$ sudo udevadm info -a -p $(sudo udevadm info -q path -n /dev/ttyUSB0)
Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.

onde eu errei? Eu não recebo /dev/CDMAModem quando eu conecto o modem.
Tente isto:
KERNEL=="ttyUSB[0-9]*", SUBSYSTEM=="tty", SUBSYSTEMS=="usb", ACTION=="add", ATTRS{bInterfaceNumber}=="00", ATTRS{bNumEndpoints}=="03", ATTRS{product}=="ZTE CDMA Tech", SYMLINK+="CDMAModem"
SYMLINK precisa da correspondência do nome do dispositivo KERNEL== e SUBSYSTEMS para ATTRS . Pode realmente funcionar sem SUBSYSTEM e / ou SUBSYSTEMS .... Movido ACTION também.
Tente algo como:
SUBSYSTEMS=="usb", ENV{.LOCAL_ifNum}="$attr{bInterfaceNumber}"
SUBSYSTEM=="tty", ATTRS{idVendor}=="1234", ATTRS{idProduct}=="5678", SYMLINK+="your_device%E{.LOCAL_ifNum}"
