Description
Ensure no device is connected to a virtual machine if it is not required. For example, floppy, serial, and parallel ports are rarely used for virtual machines in a data center environment, and CD/DVD drives are usually connected only temporarily during software installation.

ℹ️ Check
For each virtual machine do the following: From the vSphere Client, right-click the Virtual Machine and go to "Edit Settings". Review the VM's 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, the use of a USB controller and USB devices for that purpose is not a finding.

✔️ Fix
For each virtual machine do the following: From the vSphere Client, right-click the Virtual Machine and go to "Edit Settings". Select the USB controller, click the circled "X" to remove it, and click "OK". or From a PowerCLI command prompt while connected to the ESXi host or vCenter server, run the following command: Get-VM "VM Name" \| Get-USBDevice \| Remove-USBDevice Note: This will not remove the USB controller, just any connected devices.
