I recently upgraded to version 4.0. Now my peripherals will no longer work with my virtual machine running windows XP. If I plug in my printer or my GPS, I get the dialogue box, do you wish to connect this device to your mac or to your virtual machine. If I choose mac, everything works with my mac. But if I choose the virtual machine,m the dialogue box goes away as if it has gotten my message. But my virtual machine insists that the printer is off-line, and can't find my GPS. What's up? And how do I fix it?
