You can remove a USB controller from the virtual machine if you do not want to connect to USB devices.
Verify that all USB devices are disconnected from the virtual machine.
- Navigate to a datacenter, folder, cluster, resource pool, host, or vApp, and click the Related Options tab and click Virtual Machines.
- Select a virtual machine, click it again, and click the Summary tab.
- Select Virtual Hardware and expand the USB controller menu.
- Click Remove.
- Click OK to save your changes and close the dialog box.
The controller is no longer connected to the virtual machine, but remains available to add at a later time.
