That counts as "STK500 alike".  It's using the same higher-level
protocol, just on top of an USB transport instead of RS-232 with the
old STK500.

Yes, as I mentioned: have a look into the STK500 documentation.
Towards the end, there's a debugging hint.  IIRC, you can create a
registry entry denoting a log file that logs the entire programmer
communication.

In AVRDUDE, you can see the equivalent of that with -vvvv (four
options "v").
