Data Object - VirtualUSBRemoteHostBackingInfo(vim.vm.device.VirtualUSB.RemoteHostBackingInfo)

Extends: VirtualDeviceDeviceBackingInfo
Since: vSphere API 4.1

Data Object Description

The VirtualUSBRemoteHostBackingInfo data object identifies a host and a USB device that is attached to the host. Use this object to configure support for persistent access to the USB device when vMotion operations migrate a virtual machine to a different host. The vCenter Server will not migrate the virtual machine to a host that does not support the USB remote host backing capability.

Specify remote host backing as part of the USB device configuration when you create or reconfigure a virtual machine (VirtualMachineConfigSpec.deviceChange.device.backing).

To identify the USB device, you specify an autoconnect pattern for the deviceName. The virtual machine can connect to the USB device if the ESX server can find a USB device described by the autoconnect pattern. The autoconnect pattern consists of name:value pairs. You can use any combination of the following fields.

path - USB connection path on the host
pid - idProduct field in the USB device descriptor
vid - idVendor field in the USB device descriptor
hostId - unique ID for the host
speed - device speed (low, full, or high)

For example, the following pattern identifies a USB device:

"path:1/3/0 hostId:44\ 45\ 4c\ 43\ 00\ 10\ 54-80\ 35\ ca\ c0\ 4f\ 4d\ 37\ 31"

This pattern identifies the USB device connected to port 1/3/0 on the host with the unique id 0x44454c4c430010548035cac04f4d3731.

Special characters for autoconnect pattern values:

The name and value are separated by a colon (:).
Name:value pairs are separated by spaces.
The escape character is a backslash (\). Use a single backslash to embed a space in a value. Use a double blackslash to embed a single backslash in the value.

Properties

Name	Type	Description
hostname	xsd:string	Name of the ESX host to which the physical USB device is attached (HostSystem.name). When you configure remote host backing, hostname must identify the local host on which the virtual machine is running.
