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 14 USB 2.0 ports (six 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.
