HE910/UE910/UL865 use the standard cdc-acm driver.

Some useful information can be found in "HE910/UE910/UL865 Families Ports
Arrangements User Guide" (it can be found in Telit website).

The AT command AT#PORTCFG sets the ports behaviour.

For the factory setting (#PORTCFG=1) only the two interfaces I put in
the udev rules are linked to AT parsers, so I think it is safe to
ignore the other
ones.

The other ports are used with different #PORTCFG settings (for modem traces,
gps, additional AT parser, appzone...)
