if you still have a vm in that "bad" state, might be worth trying going to device manager, and right click "Scan for HW Changes". See if the vmware vhub drivers re-appear? Maybe they had just been deleted from device manager .
Do you know if the files were still on disk? or had the files been removed?
you can uninstall the usb components by doing a modify of the install from add remove programs - but you cant do this from inside a view session.
this does seem a bit odd but im sure that someone has had to do something to trigger this.
