Ack, which is why I've been working actively on moving them all over to gspca, but I need hardware access for that, see below. However this thread is about removing support for v4l1 applications, and there are actually still quite a few v4l1 apps out there, so we should not do that! > However, this does > not mean there are users who would not be using these drivers if they > actually worked or had been properly maintained.

Great! I've bene looking for someone with such a cam. As you may know I've been slowly porting over all the remaining v4l1 usb webcam drivers to gspca (removing a lot of code duplication and making them v4l2 drivers). By far the easiest way to get the driver for this camera converted to a gspca using v4l2 driver is to send it to me, would you be willing to do that ? Regards, Hans
