  • Question

  • Received Error code 6 when calling ::DeviceIoControl with command CTL_CODE(FILE_DEVICE_UNKNOWN, IOCTL_USB_INDEX(0x0000) + 4, METHOD_BUFFERED, FILE_ANY_ACCESS) on windows 10.

    Getting error on windows 10 version 1809 but same code was/is working on windows 10 version 1803.

    Is there any change in windows 10 patches? I am communicating with hardware on USB port
