But wouldn't that require at least one manual installation of the filter driver by the user, and therefore equate what we can already provide with WCID on non Windows platforms, where one WCID WinUSB driver installation is enough the make the platform behave the same way as Windows 8 in terms of detecting and automatically installing drivers? The latest Zadig can turn any XP or later platform as a WCID-enabled platform through a single driver installation. It's also not limited to WinUSB only, but will happily do libusb0 and libusbK WCID enabling too. Thus, unless, I'm misunderstanding something, going with the filter driver won't make much of a difference in terms of user experience. On the contrary, the way we are doing it at the moment ensures that we bring the same the Windows 8 WinUSB-WCID experience to earlier platforms, including the way the device will be listed in device manager, etc. All in all, as long as an initial driver installation cannot be avoided, we might as well go with the Microsoft solution. That's not to say I wouldn't be curious about an implementation of your proposal as well, but I fail to see how spending time on that will benefit us right now.
