How to install UpperFilter driver of mouhid.sys

[T.Masuda]

I want to controll our developing HID mouse from application. Does anybody
give some advice for the following questions. Any comment will be welcome.

Can I install sample moufilter.sys as an upper filter driver of mouhid.sys?
Should I change the sample source code of moufilter.sys in DDK?
How do I change inf file?

Yes

The only change needed should be whatever logic you want to implement
for your device.

Change the PnP ID to that of your device.

yes, you can use moufiltr in the ddk as an upper filter to mouhid....but as
an upper filter all you will be able to do is modify the data reported by
mouhid. if you want access to the raw HID data, you will need to be a lower
filter which behaves a bit differently. if you go the lower filter route,
the best starting point is the KMDF version of the toaster filter.

as for the INF, you should match against the generic HID mouse compatible
ID, HID_DEVICE_SYSTEM_MOUSE

Thanks a lot.

ray had a better suggestion. if you want to filter your specific device
(and not all HID devices), your INF should match your device's specific
hardware ID.
