If your system has udev, then you can add a few calls in your driver to get the /dev node created automatically. I have a couple of drivers which both do this: <http://svn.hylands.org/linux/gpio-event/module/gpio-event-drv.c> look at the gpio_event_init function (near the end of the file) <http://svn.hylands.org/linux/gpio/module/user-gpio-drv.c> look at the gpio_drv_init function (also near the end). The calls to class_create and device_create sets things up sp that udev will create the /dev node. -- Dave Hylands Shuswap, BC, Canada http://www.DaveHylands.com/ -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
