Why does my altpcie_demo application display as "PCI Device" under "Other Devices" in the Windows Device Manager for the PCI Express Avalon-ST High-Performance Reference Design?

Description

Due to a problem with the provided driver information file(.inf), the reference design Device ID does not match that expected by the driver and Message Signal Interrupts (MSIs) are not enabled. This problem causes the kit to be displayed in the Windows® Device Manager under "Other devices" as "PCI Device" with a yellow "!" warning icon next to it.
