I'm writing a small app in Windows XP to control a UVC device's input
selection via ISelector interface.

get_NumSources() works OK
get_SourceNodeId() works too and I verified it via a protocol analyzer

however put_SourceNodeId() does not seem to have any effect at all.

Does anyone have any idea what could be the reason for put_SourceNodeId() to
fail?

I don't have any hardware that supports ISelector (which is why it is
untested). Does the put call return an error code?
