Laurent, here is the reply from Bodelin: Gene, Thanks. I got the following from engineering: "We use a Cypress USB 2.0 controller, however it's our firmware code that makes the controller USB video class compliant. If he follows the rules of USB, he should have no problem creating a driver. He can look at the Microsoft XP USB video class driver as an example. Also, there's a book call "USB Complete" by Jan Axelson which may help as well." Was this helpful Gene? If not let me know what you need. - Peter It looks like that they may offer more help if asked. Thanks again Laurent -- Gene Imes ============================= ozob.net _______________________________________________ Linux-uvc-devel mailing list [email protected] https://lists.berlios.de/mailman/listinfo/linux-uvc-devel
