    Hi Ajay,

    I want to do USB communication like usb_dev_bulk from the starterware....

    My objectif is that I will bidirectional communicate with the PC (user interface) and the OMAP l138, I want a simple communication, I will send simple data and command. It's not require a very fast communication and the data will be very small.

    I need the driver soon because the compagny who developing the PC software need it now....

    Can you help me pls

    Vince,

    There are many standard and linux specific gadget driver supported by linux. You can refer at drivers/usb/gadget. There is one gadget which can be used for you purpose seems to be gadgetfs and related file is drivers./usb/gadget/inode.c You would need to read about this and write a correspoding windows pc side driver. For linux PC you can use libusb interface to talk. You can find details at http://www.linux-usb.org/gadget/
