Yes, this is really an annoying problem. I have a new MacBook Pro i7 (Mid 2010) with Windows 7 Ultimate x64. Both USB Enhanced Host controllers (3B34 and 3B3C) work fine. But these 2 USB Universal Host controllers can't be started:
"Intel(R) 5 Series/3400 Series Chipset Family USB Universal Host Controller -
3B36"
"Intel(R) 5 Series/3400 Series Chipset Family USB Universal Host Controller -
3B3B"
The driver version is 9.1.1.1013, 06/04/2009. I've already tried to update the driver using the "Intel INF Update Utility 9.1.1.1025 for Intel® 5, 4, 3, 900 Series Chipsets", which updated the driver to version 9.1.1.1020, 08/20/2009. But still no change: *"This Device Cannot Start (Code 10)"* (device manager).
The Microsoft knowledge base says in
http://support.microsoft.com/kb/943104/en: "+The Code 10 error pertains mainly to hardware and device driver issues ... Therefore, we recommend that you troubleshoot these issues by focusing on device drivers, on device configuration issues, and on hardware compatibility issues.+"
Well, the hardware seems to be ok, because when I boot to Mac OS X Snow Leopard, the USB port works just fine. But in Windows 7 several other USB software does not recognize the existence of an USB port.
*Any help from Apple or Intel is appreciated!*
Thanks!
