computer by choosing one of these options:

computer will be connected to the primary OS.
 Connect it to the active virtual machine. If you select this option, the USB device plugged
into the host computer will be automatically connected to the virtual machine that is
currently running on the host computer. When no virtual machine is running, the USB
device will be connected to the primary OS.
 Ask me what to do. If you select this option, you will be prompted to choose how to connect
