    USB: Exposing second ACM channel as tty for Nokia S60 phones. · c1479a92
    Adrian Taylor authored
    Nokia S60 phones expose two ACM channels. The first is a modem and is picked
    up by the standard AT-command interface information in the CDC-ACM driver. The
    second is marked as having a vendor-specific protocol. Normally, we don't
    expose those as ttys. (On some other devices, they may be claimed by the
    rndis_host driver and used as a network interface).
    But on S60 this second ACM channel is the way that third-party S60 application
    developers are expected to communicate over USB. It acts as a serial device
    at the S60 end, and so it should on Linux too.
    The list of devices is largely derived from:
    and includes only the S60 3rd Edition+ devices documented there.
    There are many devices for which the USB device ID is not documented,
