How to Check the USB Port on Mac Terminal

In today’s digital age, USB ports are essential for connecting various devices to your Mac computer. Whether you need to transfer files, charge your phone, or connect external peripherals, a functioning USB port is crucial. However, at times, you may encounter issues with your USB ports, and it’s important to be able to check their status. In this article, we will guide you on how to check the USB port on your Mac using the Terminal.

1. Open the Terminal

The first step to checking your USB port on Mac is to open the Terminal. You can do this by searching for “Terminal” in the Spotlight (Cmd + Space) or by navigating to Applications > Utilities > Terminal.

2. Use the `system_profiler` Command

Once the Terminal is open, you can use the `system_profiler` command to check the status of your USB ports. Type the following command into the Terminal and press Enter:

“`
system_profiler SPUSBDataType
“`

This command will display a list of all connected USB devices and their respective ports.

3. Interpret the Output

After executing the command, you will see a detailed list of connected USB devices. Look for the “USB” section to find information about your USB ports. Each port will be listed with its corresponding device name, vendor, and product ID.

If you notice any issues, such as a device not showing up or a port not functioning, you may need to troubleshoot further. Common problems include a faulty USB cable, a corrupted driver, or a hardware issue with the port itself.

4. Use the `dmesg` Command for More Information

For a more detailed analysis of your USB ports, you can use the `dmesg` command. This command displays kernel messages, including information about USB devices. To use this command, type the following into the Terminal:

“`
sudo dmesg | grep -i usb
“`

Press Enter, and you will see a list of kernel messages related to USB devices. Look for any error messages or warnings that might indicate a problem with your USB ports.

5. Restart Your Mac

If you suspect a temporary issue with your USB port, restarting your Mac can often resolve the problem. Simply close all open applications, shut down your Mac, and then turn it back on.

6. Contact Support

If you have tried the above steps and are still experiencing issues with your USB port, it may be time to contact Apple Support or a professional technician for further assistance.

In conclusion, checking the USB port on your Mac using the Terminal is a useful troubleshooting step that can help you identify and resolve issues with your USB ports. By following these simple steps, you can ensure that your Mac’s USB ports are functioning correctly and continue to connect your devices without any problems.
