Hi Doron,

Device manager never showed non pnp drivers

afik it did not show them unless you set the environment varibale named “DEVMGR_SHOW_NONPRESENT_DEVICES” to “1” and hit “Show hidden devices” in the view main menu.

>Device manager never showed non pnp drivers

“Show hidden devices” shows non-PNP kernel drivers as a separate branch n the tree.

Why do you need this? this was a hack of a very doubtful practical value.

Non-PnP driver is nothing more than a kernel plugin (loaded kmode binary), and, to list them all, there are WDK command-line tools.
