+What: /sys/class/uwb_rc/uwbN/wusbhc/wusb_chid

+ 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.

+Date: July 2008
+KernelVersion: 2.6.27
+Contact: David Vrabel <david.vrabel@csr.com>
+ 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>
+ 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 for the value to
+ use.
