Hi I Umesh new to USB protocol.
I am using the philip's PDIUSBD12 USB controller for USB communication.
I have written the firmware for it. I have already designed device which works properly ie it sends & receive the data through USB port. I want to design the same device using above IC, It is enumerating properly and giving msg "Device Configured". after that the host sends vendor endpoint request and i dont know how to respond to it?..... after that it should ask for device ID string and i have to send it, and it also i dont know how to send?..... I have to use bulk transfer protocol, how to initiate it?..... please guide me.....
