You can remove USB devices from the host if you must shut down the host for maintenance or if you do not want those devices to be available to virtual machines that run on the host. When you detach a USB device from the host, the device disconnects from the virtual machine.

Use caution when you remove USB devices from a host, for example, when you plan to do maintenance on the host. The device might still be connected to a virtual machine that migrated to another host. If data transfer is taking place, you can lose data. Also use caution when you stop or disconnect the USB arbitrator. When you disable the arbitrator, devices connected to the virtual machine become unavailable.

Make sure that the USB devices are not in use.

Follow the device manufacturers instructions to safely remove the device.

When you remove the device from the host, it is no longer available to the virtual machines that run on the host.
