Are there any contemporary reports of problems with libusb0.sys as a filter driver ? - I've not noticed any on the libusb-win32 list, just the references to the historical problems before Travis fixed it. > WinUSB > has bridged libusbK's main advantage (isoc transfer) in Windows 8.1 > so that libusbK's limited use will probably for those who like the > Windows only libusbK API. The inability to control certain aspects of WinUSB enumeration behavior (making it incompatible with some USB devices I support) makes it a non-choice for my particular application, so don't draw the conclusion that libusb0 is deprecated - it's not. > UsbDk's dynamic driver switching capability is interesting.

It's attractive from the point of view of inter-working with existing vendor devices system drivers (just like libusb0 filter mode), perhaps avoiding the need to swap drivers simply to use alternate user applications.
