OTG Guru is a free Android utility designed to provide detailed information about USB devices connected to the OTG port. The application lists essential data for each connected device, including the device path, Vendor ID (VID), Product ID (PID), class, and interfaces. This makes it a valuable tool for developers working with USB devices and drivers.

In addition to basic device information, OTG Guru offers an in-depth look at all available interfaces for each device. Users can explore the endpoints associated with these interfaces, along with their specific details. This functionality enhances the app's utility for debugging and development purposes, catering specifically to those involved in USB device creation and management.
