avrisp mkII problems

Hello

I have try to instal the libusb but windows refuse it because he doesn't have a digital signature.
Have someone a solution?

Different Windows versions behave slightly differently. Mine complains about that but there is an option to accept those drivers. Windows help forums could also help in this. I think there are no signed drivers because they cost.

Just Google: Windows unsigned drivers
