First record the symptom with the current connection and note the browser, port, battery state and device settings. If your device supports both modes, repeat the same actions using the other connection. Change only one condition at a time. A hub, cable, radio environment, driver or power-management setting can be relevant, but this website cannot identify which caused a difference. A browser disconnect event means the API lost that device, not that the cable is necessarily defective. Confirm the behavior in another application and follow manufacturer instructions for pairing or firmware.
