Hi all,
The usbserial seems to be broken for board equipped with an Atmel sam9260/9g20 Soc.
I ran the lastest version of barebox (v2014.10.0) on a USB_A9G20_LPW.
Below the trace
udc0: registering UDC driver [g_serial]
g_serial usbgadget: acm/23ba9538: can't bind, err -19
g_serial udc0: failed to start g_serial: -19
usbserial: No such device
I didn't yet investigate this issue but i was wondering if someone noticed the problem.
Greg

There have been quite some changes in the USB gadget stuff. I know
USB serial currently works with i.MX and MUSB. Does v2014.08.0 still
work? That was before the changes. If yes, I think bisecting it is
the fastest way to find the culprit.
