• The plugged USB 3.0 device may run on xHCI or EHCI mode, depending on the
operating system’s setting.
• USB 3.0 devices can only be used as data storage only.
• We strongly recommend that you connect USB 3.0 devices to USB 3.0 ports for faster
and better performance for your USB 3.0 devices.
• Due to the design of the Intel ® 8 series chipset, all USB devices connected to the
USB 2.0 and USB 3.0 ports are controlled by the xHCI controller. Some legacy USB
devices must update their firmware for better compatibility.
