stmcdc and Win 8.1?

Question asked by gustavsson.mats on May 22, 2014
Our product that uses the Virtual COM port example from STM32_USB-FS-Device_Lib_V4.0.0 comes up fine all by itself on all versions of Windows up until 8.0, but for Windows 8.1 it doesn't install until you manually feed the Device Manager the .inf copied from a computer where it did install. As far as I can understand this must mean that the driver package (to use MS lingo) is signed OK, but for some reason Windows Update in Win 8.1 refuses to find it.

Is there anybody out there that a) understands this better and can explain why? and b) knows how to get this fixed?

Thanks in advance,

/Mats
