Well, there it is then - it's official - permanently archived forever, for
the world to see - I am an idiot.

(You'll have to forgive me though, I have never ever - not even once -
peered into the Objects Block, as every time I've used GRC in the past, all
of my Instrumentation requirements have always been based around WXGUI
Blocks and not QtGUI, and on each occasion of launching, WXGUI has been the

So, thank you for pointing out nothing short of the bleeding obvious.  (At
least you kept your laughter behind the Keyboard, and didn't place it in
front...  Much appreciated!)

Onwards we march, into the next brick wall.

Grabbed a few quick Blocks to confirm a functioning and complete install. 
(A UHD Source Block and a WXGUI FFT.)

Placing, and then connecting them together, punching the 'Generate the
Flowgraph', followed immediately by the 'Execute' button - landed me against
the next issue.

'EnvironmentError: IOError: Could not find path for image:
...and at the end;
'RuntimeError: LookupError: KeyError: No devices found for ----->
Empty Device Address'...

There was a hint within the response however - a suggestion to execute a
python script found within 'home/*user*/target/lib/uhd/utils/' called,

So I went and confirmed where the launch was trying to 'find' this hex image
file, and sure enough - it wasn't there!  (Even the path to this location
hadn't been created yet...)

To be safe, I executed the .py without 'sudo' - and off it ran, fetched the
necessary file, created the required path and closed.

I then rebooted, and re-attempted my simple build with just the two Blocks

This time, a new error presented;

'UHD Error:
       USB open failed: insufficient permissions.
       See the application notes for your device.'

Thinking it may well be due to not executing the .py with 'sudo', I promptly
deleted - in its entirety - the path created initially, and re-ran the .py
under 'sudo'.

Outcome was identical - still no joy, same reported error;

'UHD Error:
       USB open failed: insufficient permissions.
       See the application notes for your device.'

Had yet another good hunt about the place - both here and within the Ettus
Mailing Lists.
Only found two hits, and from what I could understand - not relevant to this
issue at hand.

Some extra info;
Running GNU C++ v4.8.2

Again, much appreciated - the assistance from you all provided thus far...
