Hello,
Am a newbie in embedded designing and working on detection of usb devices
and sending data mostly video to it for storage in Linux. Am using the c
language. I would like to know if anyone can help me with what I need to
know for my work and if there is a source code that can help me.

Thanks in advance.

I can't read your brain wave for the moment. Why don't you just try
some of these:

mount /dev/sda1 /disk
cp * /disk

Hi, thanks for that but I need to write the usb detection code myself
because I have to save video data from a camera to it and be able to read
the video data from the usb device on an LCD or other displays. Any help
with that?

There is a standard (class) for video over USB. If your camera
follows the standard, there is code available for that:
http://www.ideasonboard.org/uvc/. If it doesn't follow that standard,
you'll either need to get details from the camera manufacturer or
reverse engineer it.

Do you want to send real-time video over USB, or just save and
retrieve files containing video data? In any case, start here and then
buy Jan's book:
