I'm having a strange problem, I can't connect _any_ USB devices to my Windows 7 VM. I don't know if it was always this way as it's a fairly new installation (a week or so). I can plug in a USB drive and I'm prompted whether to connect it to the Mac or the Linux VM but _not_ the Windows 7 VM. When I shutdown the Linux VM, the USB drive auto connects to the Mac. I can't take control and assign the USB drive to Windows 7 VM because there is no "External Device" menu item. What would cause that? Thank you, Caesar.
Also note that this VM was migrated from VirtualBox. I just tested installing brand new from the install DVD and it does have "External Devices" and can capture the USB drive. How do I get the "External Devices" menu item back? There is a lot of software installed and Windows 7 is already activated in the VM.
One more clue is when using "Action" -> "Configure" -> "Hardware" there is no "USB & Bluetooth" configuration item. Clicking on "+" doesn't list it there either.
I spoke too soon, somehow this time around "USB & Bluetooth" is listed when clicking "+". I added it and now "External Devices" works! Hope this helps somebody.
