+Description:
+ Some USB devices use a USB receiver dongle to communicate
+ wirelessly with their device using proprietary protocols. This
+ attribute allows user-space to know whether the device is
+ connected to its receiver dongle, and, for example, consider
+ the device to be absent when choosing whether to show the
+ device's battery, show a headset in a list of outputs, or show
+ an on-screen keyboard if the only wireless keyboard is
+ turned off.
+ This attribute is not to be used to replace protocol specific
+ statuses available in WWAN, WLAN/Wi-Fi, Bluetooth, etc.
+ If the device does not use a receiver dongle with a wireless
+ device, then this attribute will not exist.
