6. USB 3.1 Gen 1 (up to 5Gbps) ports.
These 9-pin Universal Serial Bus
(USB) ports are for USB 3.1 Gen 1 devices.
• USB 3.1 Gen 1 devices can only be used for data storage.
• We strongly recommend that you connect USB 3.1 Gen 1 devices to USB
3.1 Gen 1 ports for faster and better performance from your USB 3.1 Gen 1
devices.
• Due to the design of the Intel
®
300 series chipset, all USB devices
connected to the USB 2.0 and USB 3.1 Gen 1 ports are controlled by the
xHCI controller. Some legacy USB devices must update their firmware for
better compatibility.
• Due to chipset limitations, U31G1_E12 and U31G1_E34 ports share the
same 5Gbps bandwidth.
