I see your point. The idea was to give the user an override, in case the 
OSS detection isn't smart enough and refuses to load a legitimate 
implementation. If the user explicitly tells us to use OSS, then I think 
the heuristics in DllMain should be ignored; nothing in there is 
"critical" to our OSS driver.

MMDevAPI could pass some "explicit" flag to the driver, but DllMain 
doesn't take arguments (right?). It looks like we'd have to put the 
explicit flag into GetEndpointIDs and change MMDevAPI to check that 
function during driver load time, or create a new Initialize() entry point.

Do you prefer either of those options? Should I just go back to the 
drawing board on the whole idea?
