>Description:
	The following device attaches as ugen in a vanilla kernel.
	It could be so much more as a urtwn instance.

	Realtek (0xdf6) 802.11n WLAN Adapter (0x77), rev 2.00/2.00
>How-To-Repeat:
	Get your hands on this device and plug it in.
>Fix:
	See patch below. Linux calls it a rtl8192cu, so I just
	appended took the name of the R2 device that was already
	there and appended a 'b'. No idea how this is usually
	handled.
