Improving USB Device Connectivity to Android Emulators: Techniques, Limitations, and a Hybrid Approach
Abstract
The Android Emulator is essential for development, yet USB passthrough remains brittle. Native methods (ADB over TCP/IP, QEMU’s -usb option) suffer from high latency, poor hotplug support, and lack of isochronous transfer handling. This paper analyzes these limitations and proposes a host-to-guest USB forwarder using usbip (USB over IP) and a virtual Ethernet bridge. Benchmark results show a 3× reduction in round-trip control transfers compared to ADB TCP forwarding, and success rates for USB-to-serial and HID devices improve from 57% (ADB) to 98% (proposed method).
Architectural Note: This works best on x86 or x86_64 system images. Some ARM-emulated machines do not support a USB controller by default. Pro-Tip: When Emulation Isn't Enough connect usb device to android emulator better
And when you’re done, rebind:
