It is not necessary to handcraft such a device. In my case it gets created automatically when the driver of the USB web cam is loaded (hotplug). IMO, the OP's video capture device may not have a driver in the Linux kernel or the driver could be broken i.e. it gets loaded but does not create the device. (I have this problem with an old Kensington web cam). -- Arun Khan -- Arun Khan _______________________________________________ ilugd mailinglist -- [email protected] http://frodo.hserus.net/mailman/listinfo/ilugd Archives at: http://news.gmane.org/gmane.user-groups.linux.delhi http://www.mail-archive.com/[email protected]/
