Locate the USB hub that you want to disable. It will usually be listed as “USB Hub” or something similar. Right-click on the hub and select “Disable” from the context menu.
A warning message may appear asking if you’re sure you want to disable the device. Click “Yes” to confirm.
The USB hub will now be disabled. You can verify this by checking if the hub’s icon has a downward arrow on it, indicating that it is disabled.

Disabling the USB hub in Device Manager will prevent any devices connected to it from functioning. They will not be recognized or able to communicate with your computer.

If you ever need to re-enable the USB hub, simply follow the same steps in Device Manager, but select “Enable” instead of “Disable.”

Now that you have disabled the USB hub in Device Manager, you can proceed to the next step based on your operating system.

Step 4: Disable the USB hub in System Preferences (Mac)

If you’re using a Mac, you can disable the USB hub through the System Preferences menu. Here’s how:

Click on the Apple menu in the top-left corner of your screen and select “System Preferences.”
In the System Preferences window, click on the “Hardware” section and choose “USB” from the list of options.
A window will open displaying all the USB devices connected to your Mac. Locate the USB hub that you want to disable.
Select the USB hub from the list and click on the “-” (minus) button at the bottom of the window to remove it from the list.
A confirmation prompt may appear asking if you want to remove the USB hub. Click “Remove” to confirm.

By removing the USB hub from the USB device list in System Preferences, you effectively disable its functionality. Any devices connected to the hub will no longer be recognized by your Mac.

If you ever need to re-enable the USB hub, you can do so by connecting it again or by clicking on the “+” (plus) button in the USB device list and selecting the hub from the available devices.

Now that you have disabled the USB hub through System Preferences, you can move on to the next step depending on your operating system.

Step 5: Disable the USB hub in Linux

If you’re using a Linux operating system, disabling a USB hub can be done through the command line or by modifying some system files. Here’s how you can do it:

Open a terminal window on your Linux system.
Type the following command to switch to the root user:

bash
sudo -i

Enter your password when prompted.
Type the following command to list all the USB devices connected to your system:

bash
lsusb

Identify the USB hub that you want to disable based on the device information listed.
Type the following command to disable the USB hub:

bash
echo “disable” > /sys/bus/usb/devices/usbX/power/control

Replace “usbX” with the actual device ID of the USB hub that you want to disable. For example, if the device ID is “usb1”, the command would be:

bash
echo “disable” > /sys/bus/usb/devices/usb1/power/control

Press Enter to execute the command. The USB hub will now be disabled.

Disabling the USB hub in Linux through the command line will prevent any devices connected to it from functioning. They will not be recognized or able to communicate with your Linux system.
