I have two USB serial adapters that I'm using for a project I'm working on. They are both FTDI based USB-serial adapters that are supported by OS X. I am running Leopard 10.5.6 on a Mac Pro.

I understand that when I plug the adapter into a usb port I should find an entry /dev/tty.usbserial or similar with a different string in place of "usbserial". This is not happening. When I plug them in, whether to a USB hub or USB port on the Mac Pro no entries appear in /dev at all.

Both devices appear in System Profiler with correct descriptions etc.

Nothing appears in the Networking pane of System Preferences.

If I fire up VMware the serial ports are there and correctly identified and if I connect them to my Windows VM they work fine.

I wish to use minicom which I have installed using ports to access a serial device connected to my machine (without having to fire up VMware and Windows just for this simple task!), but I can't determine which serial port I should be using in minicom - given that the /dev/tty.usbserial entry is not appearing.

Could someone please advise how to get access to the serial port?

Mac Pro, Mac OS X (10.5.6)
