From the vSphere Web Client right-click the Virtual Machine and go to Edit Settings. Review the VMs hardware and verify no USB devices exist. or From a PowerCLI command prompt while connected to the ESXi host or vCenter server, run the following commands: Get-VM \| Where {$_.ExtensionData.Config.Hardware.Device.DeviceInfo.Label -match "usb"} Get-VM \| Get-UsbDevice If a virtual machine has any USB devices or USB controllers present, this is a finding. If USB smart card readers are used to pass smart cards through the VM console to a VM then the use of a USB controller and USB devices for that purpose is not a finding.
