• USB 3.1 Gen 1/Gen 2 devices can only be used as data storage only.
• We strongly recommend that you connect your devices to ports with matching data
transfer rate. Please connect your USB 3.1 Gen 1 devices to USB 3.1 Gen 1 ports and
your USB 3.1 Gen 2 devices to USB 3.1 Gen 2 ports for faster and better performance
for your devices.
• Due to the design of the Intel chipset, all USB devices connected to the USB 3.1 Gen
1 ports are controlled by the xHCI controller. Some legacy USB devices must update
their firmware for better compatibility.
