    Enumeration problem while using host driver to enumerate U3V device

    Sam_Yeh_2669756

      Hello all,

       

      I am developing a USB3 Vision camera.

      I downloaded both Fx3 firmware source and windows host driver source from the official website,

      and managed to implement new protocol or functions on them to meet U3V format.

       

      When I tried to use windows host driver to enumerate U3V device which both are modified from original source code, below two steps always causes blue screen.

      1. WDF_USB_DEVICE_SELECT_CONFIG_PARAMS_INIT_MULTIPLE_INTERFACES

      2. WdfUsbTargetDeviceSelectConfig

       

      As I know, U3V USB device has multi-interface so I think calling related multi-interface WDF function should be ok.

      Could any one give some suggestions?

      Thanks a lot.

       

      By the way, this is my first time to develop a windows driver.
