On Linux systems, the user running the emulator often lacks raw read/write access to the USB subsystem.

Here is a comparison of the methods covered in this article, to help you choose the right approach:

Connecting physical USB devices to an Android emulator is a critical workflow for developers testing hardware integrations like biometrics, thermal printers, smart cards, or custom IoT peripherals. Because standard Android Virtual Devices (AVDs) run in an isolated quick-boot environment, they do not automatically detect your computer's hardware ports. connect usb device to android emulator better

Her app, running inside the AVD, lit up: “Sensor paired. HR: 88 BPM.”

Alternatively, use with the new "USB Bridge" (experimental as of 2025). Google is slowly adding USB forwarding via Hypervisor.framework, but it’s not production-ready.

Before fixing the issue, let’s diagnose the anatomy of the problem.

Open your terminal and run the lsusb command. You will see a list of connected devices in a format like Bus 001 Device 010: ID [VendorID]:[ProductID] Device Name .
