No connection … target machine actively refused it LIBUSB_ERROR_NOT_SUPPORTED

[gboy]

I just received an STM32F303 Nucelo-64 board and am trying to run through the simple STM32CubeMX tutorial (https://visualgdb.com/tutorials/arm/stm32/cube/).  I’m working on a Windows-10 PC (relatively new – so it has the latest O/S – but I’m not sure I have all the required drivers).  Anyway, I followed the tutorial to the point of compiling the base code in Visual Studio and when I go to ‘Debug’ I get the error:

:56829: No connection could be made because the target machine actively refused it.

And when I look into the details of the connection, the following errors are listed:

Error: libusb_open() failed with LIBUSB_ERROR_NOT_SUPPORTED
Error: libusb_open() failed with LIBUSB_ERROR_NOT_FOUND
Error: open failed
in procedure ‘init’
in procedure ‘ocd_bouncer’

Online, it was suggested that I need to install the ‘WinUSB’ driver.  However, Microsoft (https://msdn.microsoft.com/en-us/library/windows/hardware/ff540196(v=vs.85).aspx) indicates that WinUSB support is already in place (?).  Is there some driver that I need to install?

Also, I am also running Bitdefender in the background.  Not sure if that was a factor.  I have since temporarily deactivated it and tried – but that did not seem to help.

Hi,

Please try using the “Test OpenOCD Settings” button (or installing VisualGDB 5.3 Preview 7). This should automatically fix the driver issues.

Ok – what is the later/more effective version:  VisualGDB-5.2r9-trial.msi or VisualGDB-5.3.7.1769.msi?  I’m guessing the latter?

Thank you.

Hi,

Yes, VisualGDB-5.3.7.1769.msi is newer than 5.2R9 (we actually recommend downloading v5.3 Preview 8 as it is even newer than build 1769).
