I already do it. I add "scull0,c,222,0" to the DEVICES variable on this
Makefile, it was created on /dev but I cannot write data to it. The
/dev/console ("console,c,5,1" on the Makefile) is writable since a "echo
test > /dev/console" prints 'test' on the console.

The rights are the same:

# ls -l /dev/scull0
crw-------    1 root     0        222,   0 Jan  1 00:00 /dev/scull0
# ls -l /dev/console
crw-------    1 root     0          5,   1 Jan  1 00:00 /dev/console
#

Any hint ?

Thanks anyway, Matt.

Regards, Josue.
