Unlike most people... I always run as root... what me worry...

A couple of items...

I'm using the debian apt-get package. Which I just did another 'apt-get 
install' on.
I did create a 'usrp.rules' file and put it in to the /etc/udev... and 
when I unplug and
replug the device I see an entry under /dev/bus/usb/005/... which has 
'usrp' as the group
name. So it looks like udev is seeing the event and creating/modifying a 
node at some
level.

If I need to do a build from svn sources, I think everything is up to a 
usable level
outside of 'gnuradio/usrp'.

And of course it is working under the 2.6.17 kernel that is sort of my 
absolute last fall back
kernel...
