Re: [Gumstix-users] usb-serial on connex

[Grahame J. <gb...@th...>]

Hi,

Mmmmm?
When connected via ttyS0, ls -laR / works perfectly as it does via 
usbnet. Pointlessly lists all the files recursively, however it creates 
lots of traffic on the ports.

Only when using usbserial connected via /dev/ttyACM0 on the computer to 
the Gumstix listening on /dev/ttygserial do I have problems. It hangs 
the port.

Once the port hangs I can drop the module "kill -9 ttyName; rmmod 
g_serial" and reinsert it "modprobe g_serial use_acm=1" I can get it 
back, but as soon as I try it again it hangs. There is something wrong here.

Has anyone had success with usb_serial on the gumstix?
Am I doing something wrong with my setup?

Cheers

Grahame
