    USB Passthrough Not Working

    williamvoyek Lurker

      On a vShpere server I'm trying to add a USB device (a USB HDD) to a guest. I have marked all USB controllers on the host for passthrough and have rebooted the host. I have added the EHCI+UHCI controller to the guest and have the guest powered on. When I try to add the device to the guest the Add Hardware wizard shows "USB Device (unavailable)" and when I select it I see "There are no USB devices available on the host."


      How can I diagnose what's going on here? I think I've followed the proper steps to configure USB passthrough but I just can't seem to get it working.
