+KernelVersion: 2.6.27
+Contact: linux-usb@vger.kernel.org
+Description:
+ Interfaces for WiMedia Ultra Wideband Common Radio
+ Platform (UWB) radio controllers.
+
+ Familiarity with the ECMA-368 'High Rate Ultra
+ Wideband MAC and PHY Specification' is assumed.
+
+What: /sys/class/uwb_rc/beacon_timeout_ms
+Date: July 2008
+KernelVersion: 2.6.27
+Description:
+ If no beacons are received from a device for at least
+ this time, the device will be considered to have gone
+ and it will be removed. The default is 3 superframes
+ (~197 ms) as required by the specification.

+Description:
+ An individual UWB radio controller.

+What: /sys/class/uwb_rc/uwbN/beacon
+Date: July 2008
+KernelVersion: 2.6.27
+Contact: linux-usb@vger.kernel.org
+Description:
+ Write:
+
+ <channel>
+
+ to force a specific channel to be used when beaconing,
+ or, if <channel> is -1, to prohibit beaconing. If
+ <channel> is 0, then the default channel selection
+ algorithm will be used. Valid channels depends on the
+ radio controller's supported band groups.
+
+ Reading returns the currently active channel, or -1 if
+ the radio controller is not beaconing.
+
+What: /sys/class/uwb_rc/uwbN/scan
+Date: July 2008
+KernelVersion: 2.6.27
+Contact: linux-usb@vger.kernel.org
+Description:
+ Write:
+
+ <channel> <type> [<bpst offset>]
+
+ to start (or stop) scanning on a channel. <type> is one of:
+ 0 - scan
+ 1 - scan outside BP
+ 2 - scan while inactive
+ 3 - scanning disabled
+ 4 - scan (with start time of <bpst offset>)

+Description:
+ The EUI-48, in colon-separated hex octets, for this
+ radio controller. A write will change the radio
+ controller's EUI-48 but only do so while the device is
+ not beaconing or scanning.

+ Controller PAL using this radio controller.

+Date: July 2008
+KernelVersion: 2.6.27
+Contact: linux-usb@vger.kernel.org
+Description:
+ Link Quality Estimate - the Signal to Noise Ratio
+ (SNR) of all packets received from this device in dB.
+ This gives an estimate on a suitable PHY rate. Refer
+ to [ECMA-368] section 13.3 for more details.
