1st attempt at USB serial port enumerator for linux

Enumerate the ACM ports which are created in /dev after plugging in the
phone.
Tested on Kubuntu (karmic koala), using 5800XM and N95.

Linux has two USB drivers of interest.
1: CDC-ACM, this loads automatically, and creates /dev/ttyACM<n> for
   the USB modem interface
2: USBSERIAL, this needs to be loaded manually using modprobe, and
   creates /dev/ttyUSB<n> for each ACM interface on the phone

The second ttyUSB port is the one we need, this enumerator does not
pick the correct port yet. (1st port is ECACM:0, i.e. the modem, 2nd
port is ECACM:1, i.e. the general purpose port used by TRK)

according to lsusb, the 1st ACM descriptor has:
class 2 (comms)
subclass 2 (abstract - modem)
protocol 1 (AT commands)

2nd ACM descriptor has:
class 2 (comms)
subclass 2 (abstract - modem)
protocol 255 (vendor specific)

Linux 2.6.33 RC3 has a hardcoded list of nokia phones in cdc-acm.c for which
the protocol 255 ACM port will be recognised as a second ttyACM
