Can anyone with this issue (USB Host Controller Passthrough) check if it's working with the latest Update http://kb.vmware.com/kb2043967 (Build 1021289)
I just tried it with a HP DL360 G7 and the controller didn't vanish after the required reboot to enable passthrough for the USB Host Controller.
On the other side we've a call open on that so maybe we'll also get official confirmation.
