## Data Object Description

The VirtualUSBUSBBackingInfo data object identifies a USB device on the host where the virtual machine is located. This type of backing supports only a local connection where the virtual machine will remain on the host to which the USB device is attached.

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.
