I downloaded the STM32CubeProg from the STM website. It appears to install a couple of USB drivers. However, it does not recognize my custom STM32F7 board that is in DFU mode. Per the User Guide I have uninstalled the DfuSe USB driver, but the STM32CubeProg still cannot see my board. If I reboot my board, the DfusSe drivers are automatically re-installed by Windows. Am I doing something wrong?
