USB Serial Ports

So, my app works fine is Mac OS X and recently a user requested a port to Linux. So, I compiled for linux....

My app listens to USB GSM 3G Modems and profiles the diagnostics of the device. Things like the connected tower, signal strength, etc. It does this via the serial port. Works fine in Mac OS X but in Linux, it lists the serial ports "/dev/tty#" but not "/dev/USB1" which is the diagnostics USB port for the device (not always 1 - could be 2 or DIAG or PCUI).

Does the compiled app simply list the tty ports or does it actually interface to list serial ports?

You can get a reference to a port that RB can not list like this:

dim Serial1.SerialPort = System.SerialPort("/dev/USB1")
