What should you do first if a newly connected USB device doesn't work after installing the driver?

Reboot the computer
Make sure the USB device is plugged in properly
Update the device driver
Try connecting the device to another port

The correct answer is: Make sure the USB device is plugged in properly

Making sure the USB device is plugged in properly is a fundamental first step when troubleshooting a device that is not functioning correctly. Often, users may overlook a simple connectivity issue, such as a loose cable or an improperly seated connection. Ensuring that the device is securely connected to the USB port eliminates the possibility of a physical connection issue before moving on to more complex troubleshooting steps, such as rebooting the computer or updating the driver. Once the physical connection is confirmed, if the device still fails to work, it would be logical to consider rebooting the computer or exploring driver updates. However, verifying that the device is properly plugged in addresses the most basic potential failure point and is the most straightforward approach to troubleshooting.
