Yes the summary is correct.

WinUSB has bridged some gaps in Windows 8.1 and now that it
supports isoc transfer, it will be even more preferred generic Windows
driver going forward.

libusbK has a gap now to support WinUSB's isoc capability.

libusb Windows backend (1.0 API) has a gap to support isoc
functionality of libusbK and WinUSB. It is also lagging behind
other OS (Linux and Mac OS X) in terms of hotplug. Hopefully
more people will join the development and review process.
