Raw PDO object as Unspecified under "Devices and Printers" window (Windows 7) RRS feed

  • Question

  • My driver has a raw PDO device that is represented as an "Unspecified" device in the user's "Devices and Printers" window.

    vJoy Driver

    The text (Model Value) is OK but the categories are 'Unknown" which is probably why the icon is generic and listed in the wrong place.

    1. How can I change the icon and move it to under "Devices"
    2. Or better, how can I replace it with per-device (minidriver) icons.

  • You don't say what type of device it is.  If you specify the class correctly it should appear in the correct place.  If you want a custom ICON create your own class and setup the icon as described in

  • you can now specify an icon per device, you don't need a custom class for that.

  • This is a RAW PDO that I use for sideband communication. I'd like to see it as a HID device. 

    Currently I have this line in my Raw device code:

    status = WdfPdoInitAssignRawDevice(pDeviceInit, &GUID_DEVCLASS_HIDCLASS);

    But it has no effect.

    However, as I mentioned above, I'd prefer having an icon per device (devices are filter drivers). Is it feasible/recommended?
