From: Aram Hăvărneanu on 1 Dec 2009 11:50
Hello,

I wish to develop 2 drivers. One will act as a virtual keyboard and the
other as a virtual mouse.

Can I start from the vhidmini sample? (src\hid\vhidmini -- it's not
available in the lastest WDK, but it's in 6001.18002). From my understanding
this is a miniclass driver that should work with kbdclass and mouclass, the
class drivers for keyboards and mice. Basically all I would need is to
generate IRPs for the class drivers to process, right?

I never worked with HID, from my understanding HID drivers don't get IOCTLs,
that's why, if you need to comunicate with the driver, you need to do it some
other way. The vhidmini sample implements such a way. Also, never working
with HID, I don't really know what/how to generate the IRPs.

One thing I don't understand is how such a driver would work with multiple
sessions.

Thanks in advance for any resources and documentation!

I decided to start from the vhidmini sample but I can't install it on Windows
7 32 bit.

I have also tried to start it with sc.exe. I have created a service with sc
create TestSrv type= kernel binPath= \path\to\vhidmini.sys and start the
service with sc start TestSrv but it fails with:

[SC] StartService FAILED 1058:

The service cannot be started, either because it is disabled or because
it has n
o enabled devices associated with it.

Btw, I could install the driver with the aid of the Toaster sample (as it's
documented in the sample Readme), however, for my application I'd like to
load and unload the driver at runtime, as needed, using the the Service
Control Manager APIs.

So why are devcon.exe, sc.exe, and the Service Control Manager APIs failing?

I had the same problem with the installation of vhidmini. Don't type
the devcon.exe ..... command directly into the command promp, but
instead create a batch file with this command inside and run it, in
this case it worked for me.
