[hylafax-users] faxaddmodem - how to specify new USB modem?

[John Hudak <jjhudak@xxxxxxxxx>]

Hello:
I am running Hylafax  4.4.4 under Ubuntu 8.04 server.
I have 4 usb ports and a Zoom USB modem configured and working.
I have a Multitech USB modem that I want to configure as a spare in case the Zoom USB modem dies.
I removed the Zoom modem, inserted the Multitech modem, and issued: lsusb, with the result:
Bus 004 Device 001: ID 0000:0000  
Bus 003 Device 001: ID 0000:0000  
Bus 002 Device 001: ID 0000:0000  
Bus 001 Device 002: ID 06e0:f107 Multi-Tech Systems, Inc. MT5634ZBA-USB-V92 MultiModemUSB
Bus 001 Device 001: ID 0000:0000

My question is: I don't know what modem identifier to give to faxaddmodem when it asks:
Serial port that modem is connected to [ttyS0]?

Should it be ttyACM0? ttyACM1? ttyUSB0? something else?

With the Zoom modem installed (and the Multitech NOT installed), running ps -lax shows getty running on ttyACM0.

Another question: Is the following a good idea to implement:
I am aware that device file names change when different USB devices are plugged in and removed. Once I
understand what usb device name I am dealing with, I plan on using udev to create a symbolic link to the modem.
With just the Multitech modem plugged in, and issuing: udevadm info -a -p $(udevadm info -q path -n /dev/ttyACM0)
I get:
