So you no longer need to do “devcon install foo.inf some\hardware-id” – you can
use the simpler “pnputil -a foo.inf”.
If you do the devcon command, you end up with both physical device objects, as
If you are writing a driver for actual physical hardware, you need to remove
the [DriverInstall32] section so you don’t get a useless PDO.
Thank you for clearing this up. No one on the [ntdev] list knew. Do you
remember when this was introduced?
I see it is actually spelled [DeviceInstall32]; I saw it in the sample INF but
didn't know what it did, mostly because it's not documented. If you have the
ability to do so, you might tell the powers that be that this very useful
section is not included in the INF documentation.
