+          WHCI is an specification developed by Intel
+          (http://www.intel.com/technology/comms/wusb/whci.htm) much
+          in the spirit of USB's EHCI, but for UWB and Wireless USB
+          radio/host controllers connected via memmory mapping (eg:
+          PCI). Most of these cards come also with a Wireless USB host
+          controller.
+
+          To compile this driver select Y (built in) or M (module). It
+          is safe to select any even if you do not have the hardware.
