Hi Dave,
Thank you for your kind reply.

I use to build under my nonpriv-account but I need the root to "insmod/rmmod".
The root account has a standard "umask" of 0022. This is:
umask -S u=rwx,g=rx,o=rx
which is not consistent with
ls -l /dev/lab1
crw-rw---- 1 root root 10, 55 2010-08-16 09:52 /dev/lab1
Even if I alter the root's umask the device is still created with the same
protection.
Here is something I do not fully understand. I have to dig more...
As you suggested as alternate method I added a udev rule:
cat /etc/udev/rules.d/70-persistent-testlab.rules
SUBSYSTEM=="misc", KERNEL=="lab[1-9]", MODE="0666"
and I get:
ls -l /dev/lab1
crw-rw-rw- 1 root root 10, 55 2010-08-16 10:30 /dev/lab1
which is what I need in order to work with this device from my account.
Thanks again,
Stephan
p.s. Nice web site!
I drew some inspiration from.
