It's /dev/ttyUSB0.  There are no others:

	$ ls /dev/ttyU*

"If the board shows up as USB ID 1457:5118, then everything
is correct." (1)

	$ lsusb -d 1457:
	Bus 004 Device 005: ID 1457:5118 First International
	Computer, Inc. OpenMoko Neo1973 Debug board (V2+)

The board should accept 8N1 at 115200 bps, but appears not to even on
systems besides Kubuntu or Debian:

A) In OpenBSD 4.4, if I try connecting, the error is this:

	$ cu -s 115200 -l /dev/ttyU0
	/dev/ttyU0: Device not configured
	link down

Same error trying ttyU[1-3]

The device is there, however:

	$ usbdevs -f /dev/usb2
	addr 1: UHCI root hub, Intel
	 addr 2: TUSB2046 hub, Texas Instruments
	  addr 3: Debug Board for Neo1973, OpenMoko

B) On OS X 10.5, I am also unable to connect with screen.  No usbmodem
devices are found when the debug board is plugged in.  Though if the
FreeRunner itself is plugged in, that shows up as tty.usbmodem5d11
