Fixed both issues... spent way too much time on this
Please note that this is for Windows 7 x64 SP1
ISSUE #1 - Drivers halting the Windows Install
RESOLUTION: Integrate update KB2685811 [KMDF - Kernel Mode Driver Framework] early in the deployment process.
My first test was conducted with MDT [Microsoft Deployment Tool] instead of LANDesk OS Provisioning to add the package under WinPE prior to the reboot in the final OS were the hardware is detected and drivers are installed.
I believe this can also be accomplished with Microsoft DISM tool to integrate permanently into the .WIM image of your OS
I'll need to find a way to do this under LANDesk.. not sure exactly how yet.
ISSUE #2 - USB3.0 drivers not detected or installed during
RESOLUTION: Integrate the USB3.0 drivers in my .WIM image (to make it available for hardware detection at the right moment)
I've added both Intel drivers iusb3xhc.inf and iusb3hub.inf with Microsoft DISM tool to make them permanent into my .WIM image of my OS.
According to my reading, eventually this could get ugly in the future if we keep adding drivers this way. Using system profiles and forcing the drivers might be a better solution in the long run... not there yet.
I hope this can help others
