USB 3.2 Gen 1 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 3.2 Gen 1 devices to USB 3.2 Gen 1 ports and
your USB 3.2 Gen 2 devices to USB Thunderbolt (USB 3.2 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.
Before connecting any Thunderbolt-enabled devices in a daisy-chain configuration,
ensure that it is equipped with one Thunderbolt™ IN port and one Thunderbolt™ OUT
port.
Due to hardware limitation, ensure to connect your DisplayPort IN cable into the
