Is the chip still soldered to the board? I guess not because of your
wording, but I really don't have any idea where these symptoms could
come from if not.

Your logs show
> Detected Bus Pirate firmware 6.2

I am not sure but I think the latest firmware is a beta firmware that
shows up as «6.2 ("v6.2-beta1")». Have you looked at that as a possible
option?

It wasn't for any of these tests, but it is right now. I put it back
to confirm it still works properly (in case I had damaged it)

The pads on the original board might not last if I desolder and
resolder a couple more times... so I've bought some SOP->DIP breakout
boards that should arrive in a couple of days.
I suppose I could just etch my own if there's any suggestions or
further tests in the mean time.

That's the firmware I'm using. The latest from their google code
downloads page, dated August 2012 - "BPv3-firmware-v6.2-r1981.hex"
