Share This:

Are you having trouble finding the USB-connected devices on your Mac? You’re not alone! Fortunately, there are several methods you can use to locate USB-connected devices and this blog post will walk you through them.

First, you can use the System Profiler found in your utility folder inside Applications. Open it up, select the Hardware header from the Contents column on the left, then select USB. The panel to the right will show all USB devices connected to your computer.

If that doesn’t work for you, Device Manager is another option. Select Windows logo key+R, then enter devmgmt. In Device Manager, highlight your computer and select Action > Scan for hardware changes.

You can also double-check your Finder settings by going to the General tab (Finder > Preferences > General) and making sure External disks are selected. Then, go to the Sidebar tab and make sure the External disks location is selected too. Close out of Preferences after that and your USB flash drive should now be listed as a location in Finder and displayed as an icon on your Desktop.

If you see “USB Devices Disabled” on your Mac, try disconnecting and reconnecting the external device or connecting it to a different port on your Mac (or directly to your Mac if it’s connected through a hub).

We hope this blog post helps you find any USB-connected devices on your Mac! If these steps didn’t work or you need additional help, feel free to reach out – we’re happy to assist!

How To Find USB-Connected Devices On Mac 1

Locating a USB Device on a Mac

To find your USB device on Mac, you can open the System Profiler from the utility folder inside the Applications folder. Once open, you will see a Contents column on the left side of the window. From there, select “USB” under the Hardware header. The panel to the right will then display all the USB devices that your Mac recognizes. If your device is plugged in, it should show up in this list with its name and information about it.

Viewing Connected USB Devices

To see all USB devices that are currently connected to your computer, you can open Device Manager. To do this, press the Windows logo key+R, enter devmgmt, and then press Enter. In Device Manager, select your computer so that it’s highlighted. Select Action, and then select Scan for hardware changes. This will bring up a list of all the USB devices currently connected to your computer.

Troubleshooting USB Connection Issues on Mac

It’s possible that your Mac isn’t finding your USB because the external disk settings are not enabled. To enable this setting, open the Finder preferences by clicking on the Finder icon in the dock and selecting “Preferences” from the drop-down menu. Then, go to the General tab and make sure the External disks item is selected. Go to the Sidebar tab and make sure that the External disks location is selected. Once you have done this, close out of the Preferences window and your USB should be listed as a location in Finder and displayed as an icon on your Desktop.

Enabling USB Devices on Mac

To enable USB devices on Mac, you will need to open System Preferences and select Security & Privacy. On the General tab, look for the section labeled “Allow applications downloaded from:”. Make sure that “Anywhere” is selected, then click the lock icon in the bottom left corner and type in your administrative password if prompted. Once this is done, USB devices should be enabled and ready to use.

Managing USB Devices on Mac

First, plug in the USB device that you would like to manage. Then, open the top-level menu of macOS and select About This Mac. From here, select System Report and then USB from the left column. Under USB Device Tree, you will be able to locate the USB device that you plugged in.

Once you can see this device in the list, you will be able to view details about it including its port number, serial number, vendor ID, product ID, and version number. You can also use System Report to identify other connected USB devices as well. Additionally, if a connected device does not appear in System Report or fails to work correctly, then you can use the macOS’ built-in Disk Utility application to troubleshoot it.

Finally, keep in mind that if you’re using an external hard drive or flash drive with your Mac computer then MacOS may ask if you would like to “Optimize Storage” when connecting it for the first time. If so, click on “Optimize” unless you plan on using that device with both Mac and Windows computers – in which case make sure to click on “Ignore” instead.

Finding Recently Connected USB Devices on a Computer

To find recently connected USB devices on your computer, you will need to open the Registry Editor by searching for ‘Regedit’ using Windows Search. Once the Registry Editor is open, navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USBSTOR in the sidebar. Here you will be able to view a list of USB devices that have been connected to your computer. The list should be sorted in reverse chronological order, meaning that the most recently connected devices will be at the top of the list.

Troubleshooting USB Not Appearing in Files

It’s possible that your USB is not showing up in your files because of a few different reasons. First, it could be that the USB drive isn’t properly seated in its port. Make sure the USB drive is firmly inserted into the port on your computer and that all connections are secure. If it still isn’t showing up, it could be that the USB port on your computer is faulty or damaged, so you may want to try a different port or try connecting the USB to a different computer. Additionally, if none of those solutions work, it could be that the USB drive itself is broken or malfunctioning. You can test this by trying to connect another device to the same port as your USB drive to ensure that it’s not an issue with the port itself. Lastly, if none of these solutions work, then it’s possible that there is an incompatibility between the file system of your USB drive and your device. To resolve this issue, you may need to format your USB drive using a compatible file system before attempting to connect it again.

Enabling USB Devices

Enabling USB devices is a simple process. First, open the Device Manager by clicking the Start button and typing “Device Manager” or “devmgmt.” After the Device Manager window has opened, click on “Universal Serial Bus controllers” to view a list of all USB ports on the computer. Now, right-click each port individually and select “Enable” to enable it. If this does not work, try right-clicking each port and selecting “Uninstall.” After uninstalling all of the ports, restart your computer and they should be re-enabled.


In conclusion, USB-connected devices are a great way to transfer data quickly and efficiently. They provide a simple, convenient connection between computers and other electronic devices. They are also compatible with a wide range of devices, from external hard drives to digital cameras and smartphones. With the use of USB ports on most modern computers, it’s easy to connect and use these devices. USB connections provide faster transfer speeds than traditional connections, making them ideal for transferring large amounts of data in a short amount of time.
