I am developing KMDF virtual com driver (in WDF) working with user mode manager that install/remove driver using devcon commands. Currently my driver runs as pnp driver without power management. However I have problem installing multiple instances of my driver. When I am loading second or further driver instance I can see that system removes previous driver instance and then loads 2 or more drivers. At the end I have multiple driver working instances however I am loosing all data stored in previous device.
Is there a good way to add new virtual PnP device? Or should I rework driver to non-PnP and try to handle it in different way?
