Did a little more searching, and in Hoop's useful thread on how to flash a Nanjg (https://budgetlightforum.com/t/-/30672), he references the flashlightwiki page, which I have to assume is wrong for the USBASP's we are buying now, but in his Post #1 he lays out the wiring for ground to go to the proper pin #10 in one set of pics/info (the clearest defined one), so maybe lots of guys have it right. Back when I started, we used flashlightwiki as the ultimate guide/ref.
Here: http://www.protostack.com/accessories/usbasp-avr-programmer, is a link to Users Guide that shows pin #3 as ground, pin #4 as TXD, but it seems clearly the doc is wrong about pin #3.
