Can't connect removable devices

Hi,

I have to think this is a simple setting somewhere.  When I use the option to connect removable devices and select a device, it shows a dialog telling me that the main desktop will no longer be able to see it (and it can't), but does not attach the device to the VM.

I have installed what I believe to be the latest VMTools (the option now shows "reinstall").

I am running Win 8.1 64 on an ASUS z87-ws MB with an i7-4770 CPU and 16 GB ram.

Any thoughts?
