The USB is to interface from microcontroller to a computer (Linux Debian).
What I intend to to is to acquire image data from OV6620 by microcontroller and send to computer by USB.
I have 2 problem here:
>> How to acquire image data DATA[0-7](beside that also have HREF, VSYN, PIXCLK): the problem is how to handle the data . I am thinking of using external interrupt to get image data.
>> How to send image data to USB interface (given microcontroller has USB interface built-in): could any one explain the USB protocol , how the USB protocol operate?
Thanks alot

@nikhilele: I need USB interface, because image transmission need high speed. Normally, people use UART to transfer image, but this is to slow. Later I want to upgrade my CMOS image sensor to 1000*1000 pixel, so I need USB that is fast enough to transfer image.
Anyway, thanks for your reply.
