I've been trying for quite a while to solve this issue. By what i've found, it seems to have something to do with libusb1, but i've installed it correctly, and yet nothing fixes it. What can i do?

Download and install libusb-win32-devel-filter-1.2.6.0.exe. I had the exact same issue and it worked for me. Also remember to use UART in sp flash tool options.

It works, thanks!
