@macnb - Try software 1.30 or ASProgrammer 1.41 (hit unlock/unprotect lock icon first, then read, verify, save)
1.30 is included in this package - http://s000.tinyupload.com/index.php?fil…213094641136166
ASProgrammer is here - https://github.com/nofeletru/UsbAsp-flash/releases/
Although, sounds like you are not getting a good connection, or you need to connect PSU cables to the board if not already (or remove them if so, sometimes you need them connected, sometimes they need to be removed)
Ahh, I see you got it, thanks for posting your solution too! Now, you can try with the above too, if you did not already (PSU cables connected)
Use USB 2.0, standard post, USB 3 may be OK but I wouldn’t try relying on this via USB 3 add-on card.
