usbtree is a cross-platform terminal user interface for inspecting USB device hierarchies.
It presents connected devices and hubs as a live, colour-coded tree with device classes, connection speeds, friendly names, port paths, identifiers, serial numbers, power requirements, and child devices.
The utility automatically detects hardware being connected or removed and records these events in a timestamped log. On Linux, it can display live device activity, measure bandwidth through usbmon, safely eject storage devices, and show PCI hardware in a separate view.
usbtree uses nusb for USB enumeration, avoiding dependencies on libusb. Basic operation does not require root privileges.
This is free and open source software.
