It is all the more right than these devices are actually operated in a fairly similar way elsewhere : through userspace extensions of similar "raw" or "misc" devices. I take the action of trying to reach a few DSLR vendors, at least the ones I have a personal reason to contact due to my equipment. I'll put my hands on it as well. Now let's face it : your great initiative has an excellent visibility, and this is a strong point to show to hardware vendors. We might need to end up with a "Linux-awareness for hardware vendors" page as a hub to kernel projects, printers/CUPS, scanners and so on. Having a separation that says "no, your support is not done here, please go elsewhere" might be an own goal, most companies tend to like having a single entry point to a service that sounds unique to them, 'hardware driving'. Now a funny thing : shooting in a studio from a camera implies getting the information shown on the rear screen. And with the generalization of Live View shooting I would not be surprised that such a device would need V4L services as well :-) -- Beno?t Donnette - Expert TM2L/OSSA - www.08000linux.com LINAGORA - 27 rue de Berri - 75008 PARIS LINAGORA recrute : http://www.linagora.com/societe/nous_rejoindre/ "A logiciel libre, rien d'impossible !"
