USB passthrough doesn't work in VirtualBox

If you've encountered difficulties with USB passthrough not functioning in VirtualBox, you're not alone. Many users face this common issue while trying to use USB devices in their virtual machines (VMs). This article aims to clarify the problem, provide a solution, and equip you with insights and practical examples to overcome this hurdle effectively.

Original Problem Scenario

The initial problem statement could be expressed as:
"USB passthrough doesn't work in VirtualBox."

Understanding USB Passthrough in VirtualBox

USB passthrough allows a VirtualBox VM to access USB devices connected to the host machine. This capability is essential for users who want to use hardware like USB drives, printers, or other peripherals within their virtual environments. However, multiple factors can lead to USB passthrough failures, such as incorrect settings, permission issues, or unsupported configurations.

Common Causes of USB Passthrough Issues

  1. VirtualBox Extensions: One of the most common reasons for USB passthrough not working is the absence of the VirtualBox Extension Pack. This extension is necessary to enable USB 2.0 and USB 3.0 support in your VMs.

  2. USB Settings: Incorrect settings in your VM configuration can prevent USB devices from being recognized. It's essential to ensure that USB support is enabled and configured correctly.

  3. Permissions: If you're using Linux or macOS, permission issues can restrict access to USB devices. You need to ensure that your user account has the necessary permissions to access these devices.

  4. Device Driver Issues: Sometimes, the host operating system might not recognize USB devices due to outdated or missing drivers.

How to Resolve USB Passthrough Issues

Here is a step-by-step guide to troubleshoot and fix USB passthrough issues in VirtualBox:

  1. Install VirtualBox Extension Pack:

    • Download the latest VirtualBox Extension Pack from the official VirtualBox website.
    • Open VirtualBox and go to File > Preferences > Extensions.
    • Click the 'Add package' icon and select the downloaded Extension Pack file.
  2. Enable USB Support in VM Settings:

    • Open your VM and navigate to Settings > USB.
    • Check the box for Enable USB Controller.
    • Choose either USB 2.0 (EHCI) Controller or USB 3.0 (XHCI) Controller depending on your device.
    • Click on the Add button (the icon with a plus sign) and select your USB device from the list.
  3. Grant Permissions (for Linux users):

    • Add your user to the vboxusers group. Open a terminal and execute the following command:
      sudo usermod -aG vboxusers $(whoami)
      
    • Log out and log back in to apply the changes.
  4. Update Device Drivers:

    • Ensure your host operating system has the latest drivers for USB devices. You may check for updates through your OS's device manager or manufacturer's website.

Practical Example

Imagine you're trying to use a USB flash drive in your Windows 10 VM. After ensuring you've followed the steps above, you should be able to access your USB device directly from your VM's file explorer. If the device still doesn't show up, try unplugging and replugging the USB drive, and ensure that it's not being accessed by the host OS.

Conclusion

USB passthrough not working in VirtualBox can be frustrating, but with a few steps, you can troubleshoot the issue effectively. Make sure you have the necessary extensions installed, verify your VM settings, and check for any permission issues. By understanding these common problems and their solutions, you’ll maximize your productivity in a virtualized environment.
