If I make device class i define ne guid.
For my device in version I use this guid.
I make section for install this class
[ClassInstall]
AddReg=_AddReg_ClassInstall
; install class, Windows 2000:
[ClassInstall32]
AddReg=_AddReg_ClassInstall
; registry entries required for class
[_AddReg_ClassInstall]
HKR,,,,"%S_DeviceClassDisplayName%"
HKR,,Icon,,"-20"
this set display name of class and icon - As icon I use standard usb icon.
