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.
