Potential issue of libusbk.sys #32

Ref: https://github.com/libusb/libusb/issues/622

The issue with libusb0.sys has been fixed in the libusb-win32 snapshot release (unsigned). Maybe libusbk.sys still has the issue.

During our trial to be compatible with HCVI mode in windows 10 version 1809 or later, we run the following command verifier.exe /flags 0x02000000 /driver (https://docs.microsoft.com/en-us/windows-hardware/test/hlk/testref/driver-compatibility-with-device-guard).

When the device using the driver libusb0.sys is plugged, it causes a bluescreen with DRIVER_VERIFIED_DETECTED_VIOLATION.

Also tested with LibusbK.sys and ended with same bluescreen with DRIVER_VERIFIED_DETECTED_VIOLATION.

libusb-win32 developer community fixed it in the following release https://sourceforge.net/projects/libusb-win32/files/libusb-win32-snapshots/20190918/ and source code in git : https://github.com/mcuee/libusb-win32/commit/9afd01fc136f1f91d94a194889886b9ebb47be1c

BTW, libusb-win32 snapshot 1.2.7.2 release has the valid digital signature. Reference discussion: https://github.com/mcuee/libusb-win32/issues/24
