I do not think so. That comment is more targeted at users of the now deprecated libusb-win32 inf-wizard (use Zadig or libusbK inf-wizard) instead. Since you have the same issue under Windows 8 x64 and Windows 7 x64, it is not a problem with Windows version. And it is also not an issue with WinUSB version. >From the debug log, it seems libusbx failed to look into the two WCID interfaces which were actually loaded with WinUSB drivers. Since there is a work around for this, I will think this is not a high priority things to debug and fix. Still I will create a ticket for this. https://github.com/libusbx/libusbx/issues/140 BTW, next time please start a new thread and not just reply to an old thread and then change the subject.
