It routes device traffic to the correct virtual machine instance for delivery to the guest operating system.

It scans the host for USB devices and manages device connection among virtual machines that reside on the host. The arbitrator is installed and enabled by default onĮSXi hosts. Manages connection requests and routes USB device traffic. When you remove the active connection of a USB device from a virtual machine, it becomes available to connect to other virtual machines that run on the host.Ĭonnecting a USB passthrough device to a virtual machine that runs on the ESXi host to which the device is physically attached requires an arbitrator, a controller, and a physical USB device or device hub. When a device is connected to a powered-on virtual machine, it is not available to connect to other virtual machines that run on the host. The device cannot connect to virtual machines that reside on another host in the datacenter.Ī USB device is available to only one virtual machine at a time. When you attach a USB device to a physical host, the device is available only to virtual machines that reside on that host. How USB Device Passthrough Technology Works

USB passthrough technology supports adding USB devices, such as security dongles and mass storage devices to virtual machines that reside on the host to which the devices are connected. You can add multiple USB devices to a virtual machine when the physical devices are connected to an ESXi host.
