OTG Guru - List USB devices

OTG Guru is an application designed for Android that provides users with the ability to identify and list USB devices connected to the OTG (On-The-Go) port of their devices. This app is particularly useful for developers and tech enthusiasts who are interested in debugging USB devices or drivers. It allows for a detailed examination of the USB devices attached, making it a valuable tool for anyone working with external hardware.

Upon launching OTG Guru, users will find a straightforward interface that displays a list of connected USB devices. Each device entry includes essential information such as the device path, Vendor ID (VID), Product ID (PID), device class, and the available interfaces. This structured presentation allows users to quickly grasp the specifications and characteristics of each connected device.

One of the primary functionalities of OTG Guru is its capability to enumerate all available interfaces for each USB device. This feature is particularly significant as it provides insight into the various communication protocols that the device supports. The app does not stop at listing the interfaces; it goes further by detailing all available endpoints associated with each interface. Users can examine the specifics of these endpoints, which is crucial for developers looking to understand how their devices interact with the Android operating system.

It is important to note that some USB devices, particularly common plug-and-play peripherals like mice and keyboards, may not appear in the app’s listings. This is because these devices are typically recognized and utilized by the operating system immediately upon connection, which prevents OTG Guru from capturing their details. Despite this limitation, the app remains effective for a wide range of other USB devices, providing a comprehensive overview of those that it can detect.

The app's utility extends to a variety of scenarios, from simple device identification to in-depth troubleshooting of USB connections. Users can leverage the information provided by OTG Guru to diagnose issues with their USB devices, ensuring a smoother interaction between hardware and software. This capability is especially beneficial for developers who need to verify the functionality and compatibility of their custom USB devices with Android systems.

In addition to its primary functions, OTG Guru serves as an educational tool for users who want to learn more about USB technology and its implementation on Android devices. By exploring the various endpoints and interfaces, users can gain a deeper understanding of how USB communication works, which can be advantageous for both personal knowledge and professional development.

The user interface of OTG Guru is designed to be intuitive, allowing users to navigate through the information with ease. The clear layout and organized presentation of data assist users in quickly locating the information they need. This focus on usability makes the app accessible to a wide audience, from experienced developers to those with a casual interest in technology.

For those who are actively involved in developing or testing USB devices, OTG Guru provides a critical resource. The app helps streamline the process of identifying and troubleshooting USB connections, which can save time and reduce frustration during development cycles. By offering a detailed breakdown of connected devices, it enables users to make informed decisions about their hardware configurations.

The application is particularly valuable in a world where USB devices are ubiquitous, and understanding their functioning can enhance user experience. Whether for personal use or professional projects, OTG Guru stands out as a practical solution for anyone needing to manage USB connections on their Android devices.

Overall, OTG Guru combines essential features that cater to the needs of developers and tech enthusiasts alike. The ability to list USB devices, provide detailed information about interfaces and endpoints, and serve as a diagnostic tool makes it a versatile application. Users interested in exploring its capabilities can easily download OTG Guru and begin utilizing its features for their USB-related projects.

By offering a blend of technical insight and user-friendly design, OTG Guru fulfills a significant niche in the Android app ecosystem, proving itself to be a beneficial tool for understanding and managing USB devices.
