USB Support
The Desktop Board supports USB 3.0 and USB 2.0. USB 3.0 is supported via two
USB 3.0 ports (blue) on the back panel. USB 3.0 ports are backward compatible with
USB 2.0 and USB 1.1 devices. The USB 3.0 ports are SuperSpeed, high-speed, full-
speed, and low-speed capable. USB 3.0 support requires both an operating system
and drivers that fully support USB 3.0 transfer rates.
There are 12 USB 2.0 ports (four ports routed to back panel connectors (black) and
eight ports routed to four onboard headers). The USB 2.0 ports are high-speed, full-
speed, and low-speed capable. USB 2.0 support requires both an operating system
and drivers that fully support USB 2.0 transfer rates.
NOTE
Intel recommends connecting USB keyboard and mouse devices to USB 2.0 ports
(black). Operating system installation may be interrupted if keyboard and mouse
devices are connected to the SuperSpeed USB 3.0 ports (blue) due to the lack of
native USB 3.0 driver support from the operating system. The device driver for the
USB 3.0 host controller must be installed from the included Intel
®
Express Installer
Driver and Software DVD before it can be operational in the operating system.
