USB Descriptor Explorer for Android

USB Descriptor Explorer (USBDevInfo) is a utility for inspecting USB devices on Android with clean, structured output. It is built for debugging, validation, and reverse-engineering.

Plug in any USB device (OTG / host mode) and instantly explore:

• Vendor ID / Product ID (VID/PID) with resolved names when available
• USB version, speed, and device class/subclass/protocol
• Full configuration, interface, and endpoint breakdown
• Power hints (Max Power)
• Input peripherals (keyboard/mouse) detection via Android InputManager

Advanced inspection (with per-device permission)

After you grant USB permission for a connected device, USBDevInfo can also retrieve deeper data such as:

• String descriptors (manufacturer, product, serial, interface strings)
• Parsed descriptor tree from raw descriptors
• Device state queries (GET_STATUS / GET_CONFIGURATION / GET_INTERFACE when supported)
• HID report descriptors with a readable summary

Perfect for USB Diagnostics

USBDevInfo helps you quickly validate what a device really reports to the host, making it ideal for:

• USB debugging and compatibility checks
• Hardware validation and QA
• Descriptor analysis for labs and security research
• Verifying endpoints, power requirements, and HID behavior
