K60 - USB Driver Signing for Windows 8

Deejay — Mon, 15 Jun 2015 01:29:40 GMT

Hi,

I'm just wondering if someone could help to get some information for me on USB driver signing for Windows 8.

I got USB working based off the K60 USB-Serial CDC example code. It uses a built in Windows driver, but it still requires an inf file which Freescale provides as part of the demo.However, while developing it I realised the inf file couldn't be installed in Windows 8 because it hasn't been signed.

I would be interested to know if Freescale has a recommended procedure for signing Windows drivers?

I can't find any information on their website or here.

Thanks.

Hi DJ,

We have no procedure for signing Windows drivers, actually this issue is not related with FSL drivers . In fact, on PC host side, to make one USB device work, MS has provided most of the drivers, what we need to do on PC host side is to let the Windows OS know which driver is suitable for this specific USB device. This is done through the .ini file.

While this .ini file is dedicated for the USB device’s vendor, for example, you need to assign the PID/VID in this ini file. Even FSL had the FSL ini file certified, the FSL PID/VID will be assigned and of course it can be used for FSL device only. For the customer who uses our chip, they may have their own PID/VID. They need to have their ini file certified by themselves.

Have a great day,
Kan

Microsoft gives a guide to self-signing a driver here: Test Signing (Windows Drivers)
