Hi folks,
Probably a simple query here, but I can’t quite seem to find an elegant
way to do what I want.
When my install app installs our drivers, it installs a bus driver,
followed by various child drivers. All of these are PnP devices, and
hence use UpdateDriverForPlugAndPlayDevices or SetupCopyOEMInf to
install and/or update the drivers for the device.
However, in some cases, I want to be able to specify that the install
app performs a “test mode” install. In such cases, it will install more
drivers than the standard install. However, it also needs to be able to
inform the bus driver to create more PDO’s for the child devices. Since
“test mode” is invoked for services (running a test version of the
drivers), I suspect what I want to do is to put a registry value in
HKLM\System\Services<our main device service>.
The problem is - how to do this cleanly? The registry key needs to be
present before the bus driver starts up, so that it creates the
appropriate child devices, but I don’t want to hack about with creating
keys in that part of the registry manually, especially if it’s a
first-time install and the specified branch of the registry doesn’t
already exist.
I’ve taken a look at QueryServiceConfig, SetServiceConfig, & also
Create/Open/Delete/ControlService functions, but can’t find a way of
cleanly doing what I want without second guessing what the PnP manager
will do with the installs.
Any ideas?

Have a 2nd INF for the test install. The 2nd INF can add the registry entries in its addreg section… for instance, from %windir%\inf\keyboard.inf
[STANDARD_AddReg.HW]
. . .
; global to i8042prt.sys (affects both keyboard and mouse)
HKLM,“SYSTEM\CurrentControlSet\Services\i8042prt\Parameters”,“PollingIterations”,0x00010003,12000
