We are developing with the Cypress EZ-USB FX2LP USB Microcontroller and we have to change the .inf file which needs to be re-certified. but there seems to be no good help on the subject we have the .inf, .spt and wdfCoinstaller01011.dll files. I am using visual studio to recompile your drivers, but when we go to the target machine it will not load because they aren't digitally signed. We can run the drivers if we by-pass the digital signature by using the Windows disable of digital signature check. We would not like to do this do very computer we have here and every time we reboot the machine. This driver will only be used in-house.

Hello,

After compiling the drivers, it needs to be certified and signed by Microsoft using the HLK Studio. Please refer to the below link for details on driver signing by Microsoft.
