Latest git: reset not supported by WinUSB. about probe-rs HOT 5 OPEN

FWIW, this is a WinUSB limitation, not just nusb.

libusb's WinUSB backend just cancels transfers and clears the data toggles but that's not at all the same as a full reset of the port. nusb's design philosophy is that it should tell you when you when it can't do something instead of poorly trying to emulate it.

nusb errors when calling reset here. I'm not sure what we can do here except not trying to reset the probe and hoping it all works out.

this seems to be a fallback to get the stlink "unstuck", see

in normal operation stlink shouldn't need a reset, and it works fine for me on Windows. I'd guess there's something else wrong with that stlink, that not even a reset can fix. the fact that it doesn't work on 0.22 either (which can do the reset) fits in with that.

it's a bug that we show that error, we should ignore if reset fails with "not supported" errors.

When connecting to a onboard ST-LINK V2-1 nucleo board which has not closed proberby by the previous program.

@vDorst could you provide exact steps to reproduce this? Maybe there's another way to get the probe unstuck.

I think I can make a simple program for that.
May take a week.
