USBView is a small program for showing the device tree of the USB bus and then displaying information about connected devices on the bus.
After nearly three years without any updates, USBView 2.0 was released this week. USBView 2.0 features GTK3 support and now uses DebugFS for reading some information rather than obsolete USBFS files. This update was needed especially with newer Linux kernels moving away from USBFS.
The release announcement of his small program was made on the kernel mailing list. The code for USBView is now over on GitHub.
