Hi Vineeth,
Thanks for the suggestion. I'm currently studying usb_dev_msc example to figure out how to update usb_dev_bulk example. However, it would be nice if I can use embedded linux. Do you know of a way to make Anstrom linux to connect to PC as a generic bulk device? According www.linux-usb.org, it seems to have been possible at some point using Gadget Zero driver. But I have not been able to make it work using the current version that comes with BeagleBone.
Thanks.
