I would appreciate if somebody would removes the driver from the linux kernel. I suggested that some years ago 2014-06-23 (just scroll down): https://sourceforge.net/p/mjpeg/mailman/mjpeg-users/?viewmonth=201406 You should also find that thread in the [email protected] and [email protected] Mailinglist archive. I know of one person that is still using this old type of card's but he uses a 2.6.x Kernel on a old machine, using old software releases. https://sourceforge.net/p/mjpeg/mailman/mjpeg-users/?viewmonth=201709 That type of card were introduced about ~20 years ago. I think it is a good moment to say goodbye to that type of cards. auf hoffentlich bald, Berni the Chaos of Woodquarter Email: [email protected] www: http://www.lysator.liu.se/~gz/bernhard
