Sure; nothing wrong with that comparison either - you're just not going to get a straightforwards apples to apples comparison. Unlike libusb, the windows api really is part of the OS; whereas libusb is a convenience library that - on windows - must use the lower level api; it's not a peer. Then again, there's no reason to care much about great convenience from a lowest-level api, so I'm not really sure what all the fuss is about: as long as the api isn't so wrong-headed to make good wrappers difficult or error prone, inconvenience seems like a fairly small price.
