Please help, my mouse class filter driver failed DTM Single Computer Display Object Test On Laptop

* Hi,
I need help very urgent. This is the first time I played with the class filter driver.
I have derived a mouse class filter driver from moufiltr sample code in WDK. The driver works fine as far as I can tell. However, the DTM test failed. The failure message looks like this “SystemFund-0200: Computers must be represented by one icon in Device Center.”

I guess this is caused by the device object created for sideband communication. How can I resolve this issue?

Any help will be much appreciated.

Thanks, zhongsheng</file:></file:>

Are you running the entire system test? Is there a reason for that?
Usually, if you are creating a mouse, you would only run the mouse tests.

Roberts,

I am delivering this product to an OEM. OEM is required to run the full system test.

Is there anyway to bypass this issue?

Thanks,

This might be a problem with the metadata package, or lack thereof, indicating that now your mouse is not an internal device

There is nothing inherent in a mouse filter driver that should cause
this kind of error. The SYSFUND-0200 requirement is “Embedded devices
in a system must report the removable/non-removable capability
appropriately.”

Is this a KMDF driver? The “Removable” bit is part of the PnP
capabilities reports by WdfDeviceSetPnpCapabilities. Your filter driver
shouldn’t have to override the capabilities, if the driver you are
filtering did it properly, although you are allowed to do so. I’m
guessing from your description that your mouse filter is creating a
control device object. A control device isn’t usually PnP, so those
capability bits shouldn’t apply.

Are you working with Mouli Shankar?

Thanks Tim,

Yes, it is KMDF driver. Yes,pnpCaps.Removable is set in WdfDeviceSetPnpCapabilities. I will try to remove this function call to see if that resolves the issue.

Thank you very much. I don’t work with Mouli Shankar. Is he an expert in this area?
