True. It works because device indicates user presence during the first 10 seconds after startup. I've missed that bit.

You need to put some effort to make it run on blue pill. Since this board doesn't have user buttons, you probably want to revert to commit e12df0f.

Yes, thanks!
FYI - device works as expected even using reset btn as user action (macOS, Chrome).
I think there might be easier to reroute/resolder reset btn to different pin and use it as user btn.

And thanks again for u2f project! Just what I was looking for)
