USB 3.0 Ports on Intel Sandy Bridge Motherboards and Operating System Installation

On the Intel Sandy Bridge motherboards including the Intel DH61BE motherboard I have noticed that keyboards and mice do not function when they are plugged into USB 3.0 ports when installing an operating system. The USB 3.0 ports are the blue USB ports. I also noticed while installing an operating system with these intel motherboards while the hard drive is plugged into a blue SATA port that the OS installation CD will not recognize that you have a hard drive present. If you have a USB keyboard and or USB mouse plugged into the USB 3.0 port which is the BLUE USB ports during the installation of an operating system, the keyboard and mouse will not function thus preventing you from installing an operating system. This is due to the fact that USB 3.0 functionality is being provided by a separate computer chip on the motherboard versus the legacy USB chip that is built in – integrated into the motherboard for the old school USB 2.0.

This means when installing an OS to ignore the blue USB and SATA ports on these intel motherboard and plug your hard drive and USB keyboard and mouse into the black ports. After you get the OS installed you can switch to using the USB 3.0 ports if you really want to but this isn’t necessary. Once the operating system is completely installed then the USB 3.0 ports will function.
