Remember when I said at HMS23 that you shouldn't need a driver to talk to a printer, it should just be a library? This here is a program on Serenum that is operating a logitech webcam. The kernel exposes a generic and permissioned USB api. Program is invoked with the device being passed over the commandline and then all of the code that does camera stuff lives inside the demo program executable. This will arrive soon as an update to all existing Serenum device that already shipped. Will get the store back up soon too. (https://serenum.computer)
