Windows cannot verify the digital signature for the drivers required for this device

I run Windows 7 64-Bit and I have a USB Device with a 64-Bit Driver, but no signature. It has a device manager entry with a yellow exclamation mark and this warning:

"Unfortunately there isn't much you can do at this point. Driver signing is required (no matter what group policy options you pick) for 64-bit Windows. In fact, if I remember right it was like this back when XP 64-bit edition was released. Your best bet is to contact the company of the device and ask them for signed drivers.

I worked around this by signing them myself. To do that I had my own Certificate Authority on my domain issue a code signing certificate that I then used to sign the drivers. While my solution used Windows Server you should be able to do something with openssl and the like. You just need to trust the root signing certificate to make it work.

Obviously with all the work involved with #2 you really should see if you can get your hands on signed drivers!

Lastly, to make sure it is a signed driver issue, reboot your machine and press F8 before Windows 7 boots and select Disable driver signing and see if your device works. If it doesn't, you have another (unknown at this time) issue."
