I cannot add any UBS devices in ESXi 5.5 installed in a new hardware with a C222 Intel chipset.
Configured USB pass trough, all ok in green, but no USB devices in the 2.0 ports is to add with Vsphere client (greyed out)
lsusb command showed nothing, also there are no mounted USB devices in cd /vmfs/volumes
Inserted supported Kingston data traveler and other flash drives.
