+What:           /sys/class/uwb_rc/uwbN/wusbhc/wusb_chid
+Date:           July 2008
+KernelVersion:  2.6.27
+Contact:        David Vrabel <david.vrabel@csr.com>
+Description:
+                Write the CHID (16 space-separated hex octets) for this host controller.
+                This starts the host controller, allowing it to accept connection from
+                WUSB devices.
+
+                Set an all zero CHID to stop the host controller.

+What:           /sys/class/uwb_rc/uwbN/wusbhc/wusb_trust_timeout
+Date:           July 2008
+KernelVersion:  2.6.27
+Contact:        David Vrabel <david.vrabel@csr.com>
+Description:
+                Devices that haven't sent a WUSB packet to the host
+                within 'wusb_trust_timeout' ms are considered to have
+                disconnected and are removed.  The default value of
+                4000 ms is the value required by the WUSB
+                specification.
+
+                Since this relates to security (specifically, the
+                lifetime of PTKs and GTKs) it should not be changed
+                from the default.
