# This file specifies udev rules to tag the type of ports on supported Fibocom
# modems such that certain ports can be ignored by ModemManager.

# Fibocom L850-GL (2cb7:0007) has 1 MBIM port and 3 ACM ports. The MBIM port
# alone is sufficient for 3GPP related functionalities. It's unnecessary for
# ModemManager to probe the ACM ports, which increases the overall modem
# probing time. We thus tag the ACM ports to be ignored by ModemManager.
