USB connection failures

uuu exits without displaying anything

It seems you’re missing the libusb-1.0.dll. Put it right in place with uuu.exe.

Wait for Known USB Device Appear

If you’ve already connected the board with your computer, pressing the RESET button might help. Also ensure you have set the bootmode jumper.


Just run uuu again without resetting the board. We don’t know why this happens, it seems to be a problem with uuu itself.
