Raw PDO shows up as unspecified device in Windows 7
in [Device Drivers]
|
From: gti4ever on 25 May 2010 03:31 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. G.

From: gti4ever on 25 May 2010 17:14 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. G. "Doron Holan [MSFT]" wrote: > report in the device caps that it should not be displayed in the UI > > d > > "gti4ever" wrote in message
From: gti4ever on 25 May 2010 18:22 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? G.

From: Doron Holan [MSFT] on 26 May 2010 14:26 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. d "gti4ever" wrote in message news:1F787B10-E30E-47F1-85D3-9FA8DD2302C2(a)microsoft.com...
