    I have a Sony USB Memory Stick Walkman. I have developed my own USBSTOR.sys
    using DDK USB Bulk driver. I can read Config/interface info.

    How does Disk.sys gets loaded after USBSTOR.sys? I mean How this GenDisk id
    is generated? Does USBSTOR.sys need to create PDO for Disk.sys? Does USBSTOR
    uses IRP_MN_QUERY_RELATIONS (BusRelations) to create PDO?
