Just checking, do you see /dev/ttyUSB0 coming up when you run 'dmesg'?

For example, 

[160749.894224] usb 2-1.2: new full-speed USB device number 35 using ehci-pci

I've built the yocto console image for my Gumstix Overo that's connected to
a Tobi board.
I get no terminal output on boot (it seems to be booting though, since blue
led flashes for a long time).

I run
$ sudo screen /dev/ttyUSB0 115200
but the screen is blank.

Does anyone have any ideas on why this might be happening and how one would
go about debugging it?
