Hi, After searching a lot figured out that to create a folder under /dev is to use a '!' as separator instead of '/' in the "fmt" argument of the device_create() call. This works with kernel 2.6.18 onwards. "test!power" => /dev/test/power Regards. _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
