USB Map

Overview

A map of your USB hardware for passthrough planning: each USB controller with its IOMMU group and whether it is safe to pass through to a VM (and which one holds the Unraid boot device), the USB 2 / USB 3 port pairs behind each physical connector, hubs, and devices with their link speed against the port maximum. Name your ports with Identify mode (plug something in, the port lights up). Thunderbolt / USB4 controllers are linked to their USB side. Read-only. Tools → USB Map.

USB Map

Identify USB ports, xHCI controllers, hubs/splitters, IOMMU groups, and expected USB standard / max speeds on Unraid. Maps PCI BDF → bus → tree, and helps plan VFIO passthrough without guessing which physical port is which.

Tools → USB Map. Read-only: it changes nothing on the system. See DOCS.md.
