It means that the USB drivers specifically libusb0.dll cannot be found. This error comes from the USB library that is used by pystlink, which is in turn used by the flashing code.

@pkendall64 and there is a way to fix it?

pkendall64 commented 1 year ago

From a bit of googling it looks like the Zadig program should fix the problem. You have to choose the WinUSB driver when running Zadig. Otherwise, you could try using the web-flasher, which does it all via the browser. It is linked from the front page of the documentation web-site https://www.expresslrs.org/
