I have exactly that BOB - it came free with the DQ860MA drivers which I notice the OP is also using.



I used the 5V (upper most one in the picture) and adjacent ground to supply the BOB (from a 5V feed from the PC power supply). When it was switched on out of interest I also checked the voltage at VDD (lower one in the picture) and it was also 5V.

Board worked fine and from what I can tell in your pictures was wired up how you have it wired up (except i didn't use the enable connection on the drives).

The reason I ended up using it (for now) was because the other one I bought -

could not be made to work despite checking with scope, multi-meter, all sorts of diagnosis. My conclusion was that it was a faulty board. So whilst you run through all the good advice about settings etc. (which hopefully is the problem) you should be prepared for the board to be faulty if all else is ruled out.
