Hi Filipe,

This was a pointer in the right direction.  This device file is actually 
created by /sbin/MAKEDEV and the configurations files it uses are found 
in /etc/makedev.d/ in particular for the device I am interested in it 
was the file 01linux-2.6.x.

I have changed this line
c $ROOT                 10 200  1   1 net/tun
to
c 0660 root vboxusers   10 200  1   1 net/tun

I am still confused as to why a udev rules exists for the device when it 
doesn't seem to ever be applied.

Thanks for the help, and have a nice day.
