UMDF filter driver for raw PDO

[gti4ever]

Hi,

I am just wondering is it possible to install an UMDF upper filter driver
for a raw PDO that is created for sideband communication for a HID device?

If so, is there any samples in DDK that can be referenced?

Thanks.

you can. I would install the UMDF driver as an FDO, not as a filter. from
there, you just interact with the PDO normally

Thanks Doron.

I have another question. I created a generic UMDF driver which can be
installed as a FDO on top of a regular KMDF driver.

However, when I tried to install it as a FDO for the raw PDO, I got an error
saying "Windows successfully loaded the device driver for this hardware but
cannot find the hardware device. (Code 41)".

Any idea?

look at the setup logs and see what went wrong. how did you try to install
the FDO? with devcon or through the device manager UI?

Thanks Doron, I found the problem in my code, it works ok now.

If you don't mind, I'd like to ask you a design question. The driver that I
was experimenting with is actually a virtual HID minidriver, that is why I
need a raw PDO to send test data to it.

I am just wondering, is it possible to create a regular UMDF + KMDF hybrid
driver and use that KMDF driver to enumerate a raw PDO as a HID minidriver?
Can this be done? I just want to get your opinion before I start implement it.

Thanks.

[Doron Holan [MSFT]]

yes, you could write a KMDF bus driver that enumerated a PDO on which you
loaded a HID stack (you can use the KMDF HID sample in the latest WDK to see
how this would work). in this case the PDO would not be raw because you
would be loading hidclass on top of it

Hi Doron,

I thought the problem went away but it turned out it only worked for Win 7.
Under XP, I am still getting the "cannot find the hardware device (0x41)"
error.

I used Devcon for the installation since it is a virtual driver. Here is
part of the log file that related to the raw PDO:

#I124 Doing copy-only install of
"{E7F5CFF5-E2C2-4A85-BE17-1951F347E07F}\TESTDEVICE\1&2D595CA7&26&01".

successfully.

Is there a limitation on XP that prevent this from working?

Thanks.

Could you post your INF file?

Try installing specifying your UMDF driver as the function driver for the
device. I.e. specify the 0x2 flag in the following AddService directive.
