I have a driver that consists of a single .inf, .cat, and .sys files. I
signed the .sys, ran inf2cat, and then signed the .cat file. Signtool verify
/kp gives the catalog file a clean bill of health, but I still get the red
dialog with the "Can't verify the publisher of this driver" warning whenever
I plug in the hardware and install the driver.

Does anyone have any idea what could be going wrong? I don't require full
WHQL certification to get rif of the warning dialog, do I?
