I haven't seen a reply to this, so I'll try a couple of suggestions. Looks
like the error code is unreasonable, but there is a bug or two...

This should really be MONOUT monoutput though it doesn't really matter.

moninInput and moninOutput need to be initialized as in
   moninInput.cb = sizeof(MONIN);
   moninOutput.cb = sizeof(MONOUT);
before registering.  I suspect this is what is causing the problem.
Also, what device were you trying to monitor?  usIndex = 0 may be invalid. 
For the keyboard, it needs to be the screen group.
