I am building a install program that includes some USB drivers that need to be signed to be installed of 64bit OSs.

I followed the signing code walk through and produced a signed catalog and was able to verify the inf file. However, when Iincluded these drivers in my install the , the drivers were loaded on the machine. When I attached the USB drvice I received the unsigned driver error. What files need to be signed and what order do they need to be signed in.? For example do all the files need to be signed before the catalog is created?

FWIW. I had to sign all the dll and sys files and then it installed.
