usbview

USBView is a utility that displays a graphical tree of USB controllers, hubs, and devices connected to a Windows system. In a Windows 10 forum thread, a user reported that USBView showed more ports than physically present on their Toshiba Satellite laptop. The utility listed seven ports while the laptop had only three physical USB ports. This discrepancy occurs because USBView enumerates all potential ports on the USB host controllers and hubs, including internal and unused ports. The tool is useful for troubleshooting USB device recognition and power issues, as it provides detailed information about each device's configuration and status. Users often turn to USBView when standard Device Manager does not reveal enough detail about USB connectivity problems.
