USB over IP adds ~10-15ms of latency. For Human Interface Devices (keyboard, mouse), this is invisible. For real-time control of a CNC machine, use QEMU passthrough instead. For 99% of apps (printers, scanners, card readers), it's flawless.
This happens when Android’s USB host stack crashes. Restart the emulator with a cold boot:
emulator -avd MyAVD -no-snapshot
This is the interesting technical solution. If the native passthrough fails (which it often does for niche hardware), you can use USB over IP software. This "tunnels" the USB signal from your Host OS to the Guest OS (Emulator).
How to do it:
Why this is better: It bypasses the often-broken QEMU USB passthrough drivers used by the emulator and lets the user-space software handle the connection.
