Hello All,
As part of our software install we are installing the Intel(R) USB 3.0 Host Controller Switch Driver (iusb3hcs.sys) on machines that have Win 7 Embedded (x64). When this driver is installed I have noticed that the USB controller behaves differently:
When shutting down (or rebooting), the controller does not completely lose power. Therefore, if I reboot or shutdown from Win7, and immediately boot to a WinPe usb stick, the driver in winpe seems to have an issue loading and the stick is not recognized.
To fix the problem I can simply unplug the machine (allowing for the controller to lose power) and then booting into WinPe the stick is recognized.
Wondering if anyone knows what OS setting or change I can make in the inf to tell the driver to make the USB Controller power down when doing a shutdown. Any help appreciated
