USB devices keep disconnecting from Mac randomly
USB disconnections mean the cable is loose, the port has debris, or your Mac needs power management changes. Check that the cable is firmly connected, clean the USB port, and disable USB selective suspend in settings. This fixes most cases.
When USB devices keep disconnecting, it's because the cable is loose, the port has dust, power is being cut to save energy, or your Mac needs a driver update. We'll check the physical connection, clean the port, and adjust power settings if needed.
