It can even re-try failed USB requests to try to find a valid response. This information is important if you are a developer or programmer who wants to design a new app or hardware program that interacts with these devices.Īnother cool thing about this software is that it can display a hex dump of the descriptors for each device, which you can then analyze by hand or run through a utility. The program also shows a lot of technical information about each individual device, including its connection status, driver description, device ID, power state and address, as well as details about the manufacturer and driver. Basically, it shows all of the relevant connection data and device properties for each of your USB devices, which can be useful for troubleshooting problems with your USB hardware. It displays detailed information about each of your USB ports and hubs in a tree format, with the option to save a full report to a text file. It works based on the Microsoft "USBView" sample application that is bundled with Windows Driver Kits. USB Device Tree Viewer is a free application that allows you to quickly and easily browse through your USB controllers and connected devices.
