Easy question: Anybody tried one of the popular/cheap USB-based video capture devices (e.g. Easycap DC60, Dazzle DVC100, etc.) on an A10 device?
Normally I would guess that since such devices work OK on regular Linux desktops/laptops, that there would be no problem -- but I know from experience with 'gphoto2' camera control that not all USB ports work well for Linux devices (i.e. never could get gphoto2 to control my Nikon Coolpix cameras on an NSLU2, though it works OK on a Pogoplug).
There is nothing more dangerous than a bored cat.
