Hello,
I need to use 2 USB 2.0 devices using each 280Mbps at the same time. In plain English, I need to have access to 2 USB 2.0 controllers.
Z87 motherboards (MB) BIOSs offered the ability of routing individual USB ports to XHCI or EHCI controllers (using the "Intel USB 3.0 mode" in manual mode). Of course, it was very convenient for my needs.
I tried out several models of Z97 motherboards (Asus, AsRock, Gigabyte), and the Intel USB 3.0 manual mode disappeared. The only way we found out to have access to the 2 USB 2.0 controllers is to disable USB 3.0 controller.
Is it a limitation of Z97 chipset or MB manufacturers didn't implement this feature yet ?
Is it possible to fine tune the USB 3.0 Host Controller Switch Driver to force a specific USB routing strategy ?
Is there any way to force USB ports or devices routing to a USB 2.0 controller under Windows 7 pro ? Or maybe under Windows 8.1, using MS USB 3.0 driver ?
Thanks.
