I have a vSphere 5.1.0 server. I'm trying to DirectPath a USB drive to a VM (I've tried this on multiple identical servers with the same results). I go to Configuration -> Advanced Settings -> Properties and check the box for both USB controllers ("Intel Corporation Patsburg USB2 Enhanced Host Controller."
After a few I refresh and they show up there but tell me I have to reboot the host for them to work. Upon rebooting the host they are no longer listed in that section, so they can't be added to a VM. I'm a little lost on what to do.
