I am no longer able to connect USB hard drives to any guest. I have the them connected directly to the host, but when I try to connect it to a guest in vSphere it is not listed. I can see the USB devices when I do a lsusb in the shell. I have verified that the USB controller is installed on the guest.
I have tried restarting the usbarbitrator service by:
/etc/init.d/usbarbitrator stop
/etc/init.d/usbarbitrator start
I don't receive any errors when it starts.
I have also restarted the host.
I am running ESXi 5.0 on a single host and the guests are on hardware version 8.
