Well creating a PDO is not necessarily a bus filter driver. If you mean a true bus filter driver where you sit atop a bus driver and attached a device to each PDO as it is created the answer is no KMDF does not.

Thanks Doron for reply. If its not possible to create PDO using filter Driver with KMDF framework. is there any other way to install bus driver which creates PDO on a existing inbox stack?

Can you explain what you are trying to do? I think you are confused on what a bus filter driver does. An example of a bus filter driver would be a filter for PCI.SYS, this would see every creation and removal of a PCI card in the system and place a filter on top of the PDO the PCI.SYS driver creates. This would for instance allow a user space application to call the filter drivers FDO to enumerate the PCI cards, and read their configuration spaces. When you ask about creating a PDO in a filter driver, it sounds like you are looking to create a bus driver on top of a device. An example of this would be a multiplexer where multiple devices all send data over a single physical device. This is not a filter driver.
