Whenever Oracle releases updates for their free virtualization software VirtualBox, we must update the extension pack to get additional features on the guest virtual machine. If you use some of the advanced features such as USB 3.0/2.0, VirtualBox RDP and PXE boot for Intel cards inside the virtual machines, then you must install or upgrade VirtualBox extension pack to the latest version.
Earlier we published a guide about installing VB guest additions on Windows 10 and how to use VirtualBox to install and test Windows 2012/2016 R2 server OS at your home PC. Normally when you open a saved or new virtual machine without updating the extension pack, you will get an error message related to USB2.0/USB3.0. In this case, the particular virtual machine can’t be resumed without removing some of the configurations or updating the extension pack to the latest version.
As shown below, if you select USB 2.0 or 3.0 support without having the latest version, you will get the following warning message.
Download the latest version of Oracle VirtualBox extension pack from the home page as shown below.
Important Note: You must install the same version that is matching the installed version of VirtualBox.
You can find the older versions under the respective version number at this location if you can’t find on the home page.
Two Methods to Install VirtualBox Extension Pack
Download the file from above link. It would be in ‘vbox-extpack’ file extension format in Windows 10 OS. Once you open the file, VirtualBox would open and ask for installation. Click install to start the installation, it will be updated automatically if you have the previous version.
You must have the administrative privilege to run this package on a Windows computer. Even you can right-click the file and select ‘Run as Administrator’.
Check out these laptops that comes with a powerful processor and having enough RAM to run virtualization software to host multiple Operating Systems at your home or office laptop.
Go to File –> Preferences in the menu, then select Extensions option in VirtualBox console. From here you can browse the downloaded extension pack and install it on Windows 10.
You can view the previously installed extension packages at the same place. Uninstalling the older version can be done here by selecting the pack and click remove button.
This installation will fix the warning message of USB 2.0/3.0 support on Oracle VirtualBox and now you should be able to start new or saved virtual machines without any issues. Another few additional features will be available now. USB 3.0 feature will allow your guest virtual machines to access the data faster from the attached physical USB drives/Disks on a host computer.
