Raw PDO shows up as unspecified device in Windows 7

Hi all,

I created a raw PDO for doing sideband communication for my HID multi-touch
minidriver. I have also installed a UMDF driver on top of that raw PDO.

What I just found is: now I have a new device shows up in "Devices and
Printers" and listed as "Unspecified" device.

Is there a way to prevent my raw PDO shows up in "Device and Printers" at
all? Or is there a way to put it under the proper category?

Thanks.

Hi Doron,

My raw pdo code is based on the WDK kbfiltr sample and the NoDisplayInUI in
WDF_DEVICE_PNP_CAPABILITIES is set to wdfTrue.

Is there any other places that I should set that?

Thanks.

I just found not setting Removalbe flag in WDF_DEVICE_PNP_CAPABILITIES to
wdfTrue seems to remove that unspecified device from "Devices and Printers".
But I am not sure this is an acceptable solution or not. Is there any
potential risk for doing this for a multi-touch device?

that is a fine solution. removable means that the child is a separate piece
of phsyical hw that can be separated from the parent and thus treated like
its own entity.
