+We had to do some group modifications to get udev devices to show up properly. Note that in lsusb:
+
+{{{
+node1-1:~# lsusb
+Bus 004 Device 002: ID fffe:0002  <--- this is the usrp
+Bus 004 Device 001: ID 0000:0000  
+Bus 003 Device 001: ID 0000:0000  
+Bus 002 Device 001: ID 0000:0000  
+Bus 001 Device 001: ID 0000:0000 
+}}}
+
+From here we had to create a usrp group, add root to it, and then throw some file in the udev rules. Like So:
+{{{
+sudo addgroup usrp
+sudo addgroup <YOUR_USERNAME> usrp
+echo 'ACTION=="add", BUS=="usb", SYSFS{idVendor}=="fffe", SYSFS{idProduct}=="0002", GROUP:="usrp", MODE:="0660"' > tmpfile
+sudo chown root.root tmpfile
+sudo mv tmpfile /etc/udev/rules.d/10-usrp.rules
+}}}
+
+'''NOTE:''' the naming convention of the rules files on the flavor of debian thats on the nodes is a little different. I made a copy of the ''10-usrp.rules'' and named it z10_usrp.rules. Not really sure which one its reading, but ehh disk space is cheap. 
+
+that being said, post actual reboot (not restarting udev as the guide suggests) ls -lR /dev/bus/usb | grep usrp yeilds:
+{{{
+node1-1:~# ls -lR /dev/bus/usb | grep usrp
+crw-rw---- 1 root usrp 189, 385 Jan 28 14:20 002
+}}}
+
+The guide claims one entry per usrp (and thus just one entry).
