Enable the USB 2.0 Controller for a Virtual Machine

The virtual machine's USB controller and high-speed USB 2.0 devices are enabled by default. Modems and certain streaming data devices, such as speakers and webcams, do not work properly unless you enable USB 2.0 support.

If your virtual machine was created using an older version of Workstation the USB 2.0 device support is not enabled. You can enable the USB controller in the virtual machine settings editor of Workstation 7.x.

Before you begin, perform one of the following tasks that apply to your configuration:

•	Verify that the virtual machine is a Workstation 6.x or higher virtual machine.

•	Verify that the guest supports USB 2.0 devices.

•	On Windows XP guests, verify that the latest service pack is installed to use USB 2.0.

If you use Windows XP with no service packs, the driver for the EHCI controller cannot be loaded.

If you do not plan to use USB 2.0 devices in a virtual machine, you can use the virtual machine settings editor to disable USB 2.0 support.

1	Select the virtual machine.

2	Choose VM > Settings.

3	On the Hardware tab, select USB Controller.
