Most people won't understand - or even need to know - most of this information, of course (we certainly didn't). We discovered our USB storage device's driver, device ID, manufacturer, volume name and mount point, power features, speed requirements, and all kinds of low-level details - more than 80, in total. Clicking any of our devices then displayed a lengthy report on it. And, curiously, another port on the same hub was highlighted with an exclamation mark icon, indicating a "device general failure", perhaps very helpful if we were troubleshooting.
They were both connected to the same hub. We could see at a glance that we had two USB-connected devices a USB key, and a mouse. We found this approach immediately provided us with useful data. Clicking any of these then displays a text report on the right with more information. On the left is a tree representing your computer, USB controllers, hubs and devices. The program has a straightforward two-pane interface.
USB Device Tree Viewer is something like a USB-oriented Device Manager, showing all your USB controllers and hubs and giving you a vast amount of detail on everything connected to them.
