My Vsphere esxi 5.5 Server is no longer seeing USB devices. I shut down the server using the F12 shut down command and switched back on and one of my VMs relies on a USB licence dongle. I have tried various USB sticks (memory sticks) in all four ports and it seems Vsphere just will not see them. I tried the lusb command but it shows nothing.
USB is switched on in BIOS and it all worked until I shut down.
Does anyone have any ideas here?
