2. Click Sounds and Audio Devices.
3. Click the Hardware tab.
4. Double-click the name of your CD drive.
5. Click the Properties tab.

USB Connectors
HINT:
If you attach a USB device that was not included in your original computer order, you may need to install a specific driver to make the device
work. Check the documentation that came with the device or contact the USB device manufacturer for more information.
Although any USB device can be attached to either the front- or back-panel USB connectors, Dell recommends using the front-panel USB connectors for devices
that you frequently connect and disconnect, such as USB digital cameras and gaming controllers. Use the back-panel USB connectors for devices that you
rarely connect and disconnect, such as USB printers, scanners, mouse, and keyboards.
