Documented selection limits

Match the exact host interface, peripheral/device protocol, connector, firmware, OS/driver and power requirements before ordering. Published maximum rates are interface limits, not guaranteed application throughput. No universal device or current/future OS compatibility is implied. This is a PCI Express USB host-controller card, not an external USB hub. Match electrical PCIe generation/lane width and physical slot/profile. Per-port and aggregate bandwidth/power depend on the controller topology and auxiliary power. USB-C ports do not imply USB Power Delivery or display output.
