Recently when I opened a saved Windows 7 virtual machine in VirtualBox 4.0.2 after the update, it showed a message about ‘ Oracle VM VirtualBox Extension Pack’ for better USB2.0 support. Its because of updated 4.0.2 version and features. The warning message did not give proper information of downloading and installing this package. This small guide shows how to download and install Oracle VM VirtualBox Extension Pack in Windows host machine. Here is the message,
Implementation of the USB 2.0 controller not found!
The device will be disabled. You can ignore this warning but there will be no USB 2.0 support in your VM. To fix this issue, either install the ‘Oracle VM VirtualBox Extension Pack’ or disable USB 2.0 support in the VM settings
Its always better to have a guest operating system inside desktop virtualization software with USB 2.0 support for faster data transfer.
