If you connect a device to a USB port and it works intermittently, what should you check first?

The USB port for physical damage
The status of the device's warranty
The integrity of the device drivers
Whether the device is compatible with the OS

The correct answer is: The USB port for physical damage

When a device connected to a USB port is functioning intermittently, the first step in troubleshooting should focus on the physical state of the USB port itself. Inspecting the USB port for physical damage is crucial because any visible harm—such as bent pins, debris inside the port, or cracks—can lead to poor connections or intermittent functionality. A damaged port can disrupt data transfer and power supply, causing the device to work inconsistently. Conducting this simple check can help confirm whether the issue lies with the port or if it might be related to other factors such as the device or its drivers. While examining the warranty, checking device drivers, and ensuring compatibility with the operating system are all important parts of troubleshooting for various issues, they should follow after confirming the physical integrity of the USB port. Physical checks often reveal problems more swiftly than software or compatibility concerns, making it the logical starting point in this scenario.
