What usb device? Why can't you just store it in usb mass storage
device?

Hi Linnix,
Thanks for the questions. I want to write the program such that any device
that has a usb interface and storage can be used to store the video data.
That is why am not restricting myself to usb mass storage device.

Any inputs?

Thanks again for your concern.
