+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.

+What:           /sys/class/uwb_rc/uwbN/wusbhc/wusb_phy_rate
+Date:           August 2009
+KernelVersion:  2.6.32
+Contact:        David Vrabel <david.vrabel@csr.com>
+Description:
+                The maximum PHY rate to use for all connected devices.
+                This is only of limited use for testing and
+                development as the hardware's automatic rate
+                adaptation is better then this simple control.
+
+                Refer to [ECMA-368] section 10.3.1.1 for the value to
+                use.

+Date:           June 2013
+KernelVersion:  3.11
+Contact:        Thomas Pugliese <thomas.pugliese@gmail.com>
+Description:
+                The device notification time slot (DNTS) count and inverval in
+                milliseconds that the WUSB host should use.  This controls how
+                often the devices will have the opportunity to send
+                notifications to the host.

+What:           /sys/class/uwb_rc/uwbN/wusbhc/wusb_retry_count
+Date:           June 2013
+KernelVersion:  3.11
+Contact:        Thomas Pugliese <thomas.pugliese@gmail.com>
+Description:
+                The number of retries that the WUSB host should attempt
+                before reporting an error for a bus transaction.  The range of
+                valid values is [0..15], where 0 indicates infinite retries.
