To connect USB human interface devices (HIDs) to a virtual machine, you must configure the virtual machine to show all USB input devices in the Removable Devices menu.
By default, USB HIDs, such as USB 1.1 and 2.0 mouse and keyboard devices, do not appear in the Removable Devices menu in a virtual machine, even though they are plugged in to USB ports on the host system.
An HID that is connected to a virtual machine is not available to the host system.
Note:
You cannot configure a shared or remote virtual machine to show all USB input devices.
Prerequisites
Power off the virtual machine.
If you are using a KVM switch for a mouse or keyboard, disable automatic connection of USB devices. See Disable Automatic Connection of USB Devices.
