Hello,

The serial-over-USB is working perfectly on the Gumstix but you need 
the appropriate driver for your USB-to-serial chip. Linux supports a 
lot of these devices, a few that I own & use are TUSB3410, CP210x, 
FTDI...
You need to compile the driver(s) by doing a:

make menuconfig

in the linux directory of the buildroot, then in "device drivers" > 
"usb" there should be a lot of options (sorry if I can't recall the 
exact path), look for "usb to serial converter" and enable the drivers 
you'd like to be compiled in the sub-menu.
And that's it, after the reflashing the Gumstix should load the 
appropriate driver automatically and a "ttyUSBx" should be in /dev/ 
when you plug-in the USB serial device.

Hope this helps,
Julien.
