All,
I also need to get some data out of my
enumeration. I need to get the bus number, slot number, and function. I
don’t think I can garner that info from the DevNode interface, can I?
Thanks,
John Hirschi

Michal,
Thanks! You put me on the right path. In
order to use the CM_Get_DevNode_Status() function, I had to use the
CM_Locate_DevNode() function. The results of CM_Locate_DevNode() gave me
what I needed.
Thanks again,
John

Try to examine device status using
CM_Get_DevNode_Status() function. It
should be possible to distinguish working
adapters from others. I’m not
quite sure now, but think that
DN_DRIVER_LOADED with DN_HAS_PROBLEM and
actual problem value should be enough to
find if adapter is working or not.
