My issue was different and it was with a very old version of libusb.

Your issue might be similar to this one, some drivers may make libusb
Windows not working.

You may want to post the debug log here with LIBUSB_DEBUG=4.

Or you can create an issue with libusb here with the debug log (latest
version of
openocd binary snapshot and libusb-1.0.24 (or better libusb-10 git head).
