stbridge setup.py

Noticed two issues:
1.) Setup.py not working due to missing LIBUSB path.
2.) While trying to run alltest.py, it was unable to go pass line 5. Found this error due to BRG_USB_COMM_ERR. Totally clueless on what went wrong as I checked the COMPORT is okay.

Are you setting CMAKE_TOOLCHAIN_FILE when building? With correct installation of vcpkg, libusb should be on the path.

The error you're seeing indicates a USB communication error https://github.com/dragonlock2/STLINK-V3-BRIDGE_libusb/blob/1e1a1ae15b70f06cd16b36170b1296bee6520b58/src/bridge/bridge.h. It's possible the libusb DLL isn't being picked up.

I see. I tried to hardcode the CMAKE_TOOLCHAIN_FILE path, and now the error is BRG_ERROR:1 which translates to 'USB Connection Error'. Could it be due to the os that I am using is Windows?

    if "CMAKE_TOOLCHAIN_FILE" in os.environ:
        cmake_args.append(f"-DCMAKE_TOOLCHAIN_FILE=C:\DEV\vcpkg\scripts\buildsystems\vcpkg.cmake")
        #cmake_args.append(f"-DCMAKE_TOOLCHAIN_FILE={os.environ['CMAKE_TOOLCHAIN_FILE']}")

No it's working on my Windows computer. Did you use Zadig to change the driver for the device to WinUSB?

[mcwoo888]

Yes, I have tried to reinstall the ST-Link Bridge interface to latest WinUSB (v6.1.7600.16385).
I am actually using STLink-V3Set programmer and my main intention is to try to toggle the GPIO pin on V3Set programmer High/Low. Below are the logs that I printed out. Noticed it is able to read SN, PID, VID information on V3Set programmer, means communication is there. Just unsure, why it always failed to go pass the initialization step.

I've tried a V3SET on my end and also updated to the latest firmware and they all seem to work. Can you try installing WSL or rebooting into Linux and trying that?
