• We strongly recommend that you connect your devices to ports with matching
data transfer rate. Please connect your USB 3.2 Gen 1 devices to USB 3.2 Gen 1
ports and your USB 3.2 Gen 2 devices to USB 3.2 Gen 2 ports for faster and better
performance for your devices.

1 ports are controlled by the xHCI controller. Some legacy USB devices must update
their firmware for better compatibility.
