+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.
