Probably all *usb.inf files have the same structure, but another test have made me so confused...
I've had no yellow "!' devices when installing at Q57 chhipset (ibexusb.inf)...
But I can not determine (before next monday) if all USB devices were installed as "Intel(R) 5 Series/3400 Series Chipset Family USB Universal Host Controller" or Standard/Generic Universal (or Open, like the .inf file tells) Host controllers.
Finally: Probably ibexusb.inf is affected by the same "bug", but (firstly) installatin worked fine.
Looking inside ibexusb.inf, I've found only one difference from anothers (ichausb.inf and others with OHCI):
ibexusb.inf: [USB2.NT] sections are described before than [USB.NT] sections.
another *usb.inf: [USB.NT] sections are described before than [USB2.NT] sections.
I'm going to look for Device Manager of Q57 next monday and post the answer about installation...
