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
[160749.994450] usb 2-1.2: New USB device found, idVendor=0403, idProduct=6015
[160749.994457] usb 2-1.2: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[160749.994462] usb 2-1.2: Product: FT230X Basic UART
[160749.994466] usb 2-1.2: Manufacturer: FTDI
[160749.994469] usb 2-1.2: SerialNumber: DB00449V
[160749.997955] ftdi_sio 2-1.2:1.0: FTDI USB Serial Device converter detected
[160749.998018] usb 2-1.2: Detected FT-X
[160749.998024] usb 2-1.2: Number of endpoints 2
[160749.998029] usb 2-1.2: Endpoint 1 MaxPacketSize 64

Hello,

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?

Andreas
