Hi,
I want to filter the key reports from a usb keyboard. e.g. 1 is pressed,
but I should report 2 to the up applications. The keyboard is from a
external usb device. There is a ps/2 keyboard attached in my system
already.
I downloaded ctrl2cap, it works well. And, it could also install the
filter driver come from the Walter Oney's book. But it installed the
driver as class filter. So, the driver filtered both keyboards.
Then, I modified the firefly.inf from the ddk samples and try to
install the driver from Walter Oney's as device filter. The
installation process finished successfully, but it seems not
working(there is nothing printed in dbgviewer.).
Is there a way to install a filter driver only for a device? And, how
to? Or, maybe I made some mistakes?
Advance Thanks!

IRPMNQUERYDEVICERELATIONS request and it is not possible (usefull??)that a higher driver (FDO) in the stack can answer. I heard an opinion (I might be wrong, it seems from a Walter Oney's sample) that a (bus?) filter can put something there, so the bus driver should append its PDO's to those put by the filter. It is not surprising.

- Windows DDK from an upper keyboard filter driver i.e attaching to the i8042 port driver to another upperfilter driver (?) attaching above the keyboard class driver ( kbdclass.sys ). I was wondering if there would be a lot of work involved? It seems pretty easy. As of now, the kbfiltr filter driver attaches to the device stack by doing something.
- Control access to software only drivers. Security checklist item #3: If a software-only driver is going to be created, additional access control must be implemented. Software-only kernel drivers do not use plug-and-play (PnP) to become associated with specific hardware IDs, and can run on any PC.
