The modem is recognized successfully in default filter mode.
Looks like we need to improve our strict filter somehow to catch this one. The current logic doesn't catch it because this device has only 3 TTYs, so just looking at the ports it exposes it could really be some other thing instead of a modem, so the strict filter ignores the device. Could you get us more info from the device, e.g.: $ sudo udevadm info -p /sys/class/tty/ttyUSB0 $ sudo udevadm info -p /sys/class/tty/ttyUSB1 $ sudo udevadm info -p /sys/class/tty/ttyUSB2 $ sudo udevadm info -p /sys/class/tty/ttyUSB0 --attribute-walk $ sudo udevadm info -p /sys/class/tty/ttyUSB1 --attribute-walk $ sudo udevadm info -p /sys/class/tty/ttyUSB2 --attribute-walk $ sudo lsusb -v -d 19d2:0117 This kind of modem is a good example of a modem we expected to lose when using the strict mode.
