Template:USB Port Testing
Laptops should have at least two functioning USB ports.
☐ Note the number of USB ports on the system. Look for any physical damage, gunk, or oxidation around the ports.
☐ Use a USB mouse to test each port. Make sure you can move things around and switch between windows with the mouse cursor.
☐ If there is a broken port, make a note on the Keeper Label to be included in the
printme notes, and cover the port with black electrical tape.
Note: Some ports may seem to work but are missing the internal plastic guide the protects the metal pins. These are considered damaged because the pins are unprotected and may short out, causing damage to the USB device or the laptop motherboard. Please point out any damaged ports to your instructor.
- Run the command
lsusbin a terminal to see if devices attached to each port are recognized by the operating system.
- Check BIOS to make sure that all USB ports are enabled.
