Update 2… I give up, after spending a lot of hours getting it to work.
I have googled for the error message, it pointed me to a hint about USB 3 being unsupported. So I tried a “cheap USB hub”, as advised – no change.
So I googled some more… And downloaded the “Pocket AVR Programmer” tool, and set the “Unknown Device #1” to “libusb-win32” and tried my luck again. - https://learn.sparkfun.com/tutorials/pocket-avr-programmer-hookup-guide
Result: One blink doesn’t even run the demo app any longer, it’s just dead. I cannot “start” it with a fork either, it does not light up any more. Also, after a “promising” start, at least something changed, now all I get:
“avrdude: Yikes! Invalid device signature. Double check connections and try again”.
This now happens for every blink I tried and I’m afraid of breaking some more. So instead of being able to access more games than with the “regular” blinks, I now spend a lot of time fixing the “button” and trying to program that thing to get at least one working game – no chance.
I give up. This sucks.
