It’s a pure virtual driver without real hardware. Would there be a
different answer depending from this? A different way to set the
format for virtual or real hardware drivers?
Absolutely. The command "devcon install" sounds very inviting, but it
doesn't always do what you think. It pre-installs the driver package,
and then it creates a new fake devnode with the hardware ID you give
it. It then starts the PnP process to find a driver for the devnode it
created, just as if you had plugged in a brand new device.
It always creates a new devnode, even if one already exists. It's very
easy to end up with duplicates. If you change your INF, you must be
careful to remove the old fake devices.
