    You didn't follow the instructions. You don't install this driver using "devcon install", you install it by right-clicking the INF and choosing "Install".

    In order to correctly install an AVStream driver, one has to register several device interfaces. In the newer DDKs, that's done using the AddInterface statement. Before that statement was available, one had to run StreamingDeviceSetup in streamci.dll. The avssamp.inf only does that in the [DefaultInstall] section, which is what the right-click install does.

    Be sure to uninstall the devices you already have from Device Manager.

    Are you aware that the 7600 DDK you're using is 10 years old? It's an antique.

    Thank you so much, I thought "devcon install " is perfect way to installing driver before. Now I know I was wrong.

    There are so many books only talk about old version DDK, so I have no choice, MSDN is boring for read in my opinion. :)
