Install libusb-win32 driver on Windows 8 without a digital certificate

2.8k Views Asked by At

I am trying to write an installer for an application that includes the installation of libusb-win32 on Windows 8.

I have encountered the fact that Windows 8 requires driver packages to have a CAT file but I don't have a digital Certificate.

The option to disable the digital signature checking on Windows 8 or using Zadig are not useful in my case.

So, is it possible to use libusb-win32 on Windows 8 without a digital certificate?

Starting in Windows 8 drivers need to be signed - see duplicate post: In Windows 8, will third-party INF driver files require a signature?.

You can check this link to disable the driver signature enforcement. After disabling it, the un-signed libusb-win32 driver can be installed. I tried and it worked for me on a Windows 8.1 X64 box.
