AddDevice function in a virtual device driver

Question

Hi.

I am newbie in driver's dev field.

I need to create driver of a virtual device. And I don't know: how will an my AddDevice function be called?

Answer 1

Typically, your AddDevice routine gets called because your virtual device is enumerated by the system root bus when the system boots. Your hardware ID would be of the form "ROOT\my-virtual-device-name". There are several examples of this in the WDK samples.

Answer 2

devcon install will create a root enumerated for you, see the tool help for the exact command line. you will need an INF as well. The toaster function project in the toaster sample is a good place to start (this driver can live on a root node as well as on the toaster bus). you don't need to use the toaster bus project.
