Windows 10 incompatibility for libusb-win32 1.2.6.0/libusbK 3.0.7.0 binary with Code integrity checks

[kartrophy]

Hi,

We are currently using the latest version libusb-win32 1.2.6.0 binary (from https://sourceforge.net/projects/libusb-win32/files/libusb-win32-releases/).

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 <driver.sys> (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.

Can you please help us to solve this issue and to be complaint with windows 10 HCVI mode?

Thanks in advance for your help.

Karthiga.

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

strange i had no issue with libusbk driver (generated by libusbk inf wizard or manualy ) on many win10 system
maybe you can try installing with zadig (libusb-win32 or libubsuk ) see if it does the same ?

anyway that is not a libusb issue but a driver install porblem.

i install libusbK through zadig. Did you try to load it after activating this driver in the driver verifier with code integrity verification? In normal use, i have no issue.

the issue is located in the libusb0.sys and lisusbK.sys.

no never did it , i do "simple" install and use ;)

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 : mcuee/libusb-win32@9afd01f

Thanks a lot for this prompt support and release!
