Hmm, that is strange. libusbk-inf-wizard and Zadig both install libusb0.dll
and libusbK.dll to be compatible with libusb-win32 and libusbK.

As for libusb Winodws backend, it will work either with libusbK.dll (to
support libusb0.sys, libusbK.sys and WinUSB) or without libusbK.dll
(only works with WinUSB). The code path will be a bit different.

Are you using the latest release version of libusb (1.0.18)?
