Hi all,

I am wondering if there's any user-mode APIs that can enumerate all
devices under PCI bus. I saw it in Computer management tool ( mmc.exe
) that they can show all the devices under PCI bus, and they can
rescan any plug-and-play hardware changes. Does it only re-scan the
registry or really scans the bus? Is it using undocumented functions
in mmcbase.dll? Any help would be highly appreciated.

Platform: 9x, 2000, xp
