About this app

Use OTG Guru to get a list of the USB devices connected to the OTG port.

For each device, the app will display:
• path
• VID, PID
• Class
• Interfaces

The app will list all the available interfaces.
For each interface, the app will list all the available endpoints and their details.

Please note:
Some "plug and play" USB devices like mouse or keyboard might not get listed in our app, as they get immediately used by the operating system.

We hope that you will find the OTG Guru useful for developing or debugging USB devices or drivers.

If you are a tech enthusiast 👨‍💻, make sure to check our other apps as well, you will find some great tools 🔧🕹️💡🤖

Does exactly what it says, which is refreshing, and what I needed, which is important. But note, this is a techie tool - don't expect any handholding, this gives you raw info.

Doesn't work. As I type I have my wireless LED mouse plugged in to my Motor G Stylus with a C-Type OTG and your remidial app says 0 devices even after a force close??? I would pay someone for uninstalling this app.
