Problem mapping VB com code to Python

No luck, I have tried all possible case combinations and permutations
of what I see in the com brouser. The only place I have found
references to the com module qbFC2_1Lib is in the "Registered Type
Libraries".
Is there another way to access the com module then client.Dispatch()?
What is the mapping of the VB statememnt
" Dim sessionManager As New QBFC2_1Lib.QBSessionManager"
does this imply something other than late binding.
When I ran makepy it generated a file containing lots of information
about the module, I don't know how to figure out what it means.
How is the output of makepy used, can it tell me something about how
to connect to the corresponding COM module>
I am really at a loss here, I don't understand enough about COM or VB
to figure this out.
