Recently , I am learning about VAD development and have a question of device stack construction.
In the procedure of the construction of Device stack , bus FDO is able to detect the attached devices , and create the PDO of the device and accordingly trigger the loading of device driver … But as for a virtual device (saying VAD) the bus doesn’t detect it and impossible know when the PDO of virtual Device will be created , not to mention FDO.
My question is when/who will trigger loading virtual device driver.
Please someone share some ideas. thanks a lot .
