The windows USB disconnect & reconnect you hear is the wheelbase attempting to recover from a monitored instability on the USB bus.
This is programmed into the firmware if a certain % of heartbeats between the PC & wheelbase fail within a defined period. It seeks to highlight USB issues rather than being the cause.
Can you post screenshots of your Telemetry page whilst in AMS2. One screenshot after you exit the garage and another after the issue occurs.
Do not switch USB modes before taking the 2nd screenshot.
Further question, when the hard left or right occurs, does the wheel remain at full power (pushing against the endstops) after the disconnect/reconnect?
