An "N" upper letter is not a wildcard, nor can easily be identified by script, specially since the USB sysfs define things like. bNumInterfaces. Use, instead, <N>, in order to let script/get_abi.pl to convert it into a Regex.

What: /sys/class/uwb_rc Date: July 2008 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.
What: /sys/class/uwb_rc/uwb/ Date: July 2008 KernelVersion: 2.6.27 Contact: linux-usb@vger.kernel.org Description: An individual UWB radio controller.
What: /sys/class/uwb_rc/uwb/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/uwb/ASIE Date: August 2014 KernelVersion: 3.18 Contact: linux-usb@vger.kernel.org Description:
The application-specific information element (ASIE)
included in this device's beacon, in space separated
hex octets.
Reading returns the current ASIE. Writing replaces
the current ASIE with the one written.
What: /sys/class/uwb_rc/uwb/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>)
== =======================================
What: /sys/class/uwb_rc/uwb/mac_address Date: July 2008 KernelVersion: 2.6.27 Contact: linux-usb@vger.kernel.org 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.
What: /sys/class/uwb_rc/uwb/wusbhc Date: July 2008 KernelVersion: 2.6.27 Contact: linux-usb@vger.kernel.org Description: A symlink to the device (if any) of the WUSB Host Controller PAL using this radio controller.
What: /sys/class/uwb_rc/uwb// Date: July 2008 KernelVersion: 2.6.27 Contact: linux-usb@vger.kernel.org Description: A neighbour UWB device that has either been detected as part of a scan or is a member of the radio controllers beacon group.
What: /sys/class/uwb_rc/uwb//BPST Date: July 2008 KernelVersion: 2.6.27 Contact: linux-usb@vger.kernel.org Description: The time (using the radio controllers internal 1 ms interval superframe timer) of the last beacon from this device was received.
What: /sys/class/uwb_rc/uwb//DevAddr Date: July 2008 KernelVersion: 2.6.27 Contact: linux-usb@vger.kernel.org Description: The current DevAddr of this device in colon separated hex octets.
What: /sys/class/uwb_rc/uwb//EUI_48 Date: July 2008 KernelVersion: 2.6.27 Contact: linux-usb@vger.kernel.org Description:
The EUI-48 of this device in colon separated hex
octets.
What: /sys/class/uwb_rc/uwb//IEs Date: July 2008 KernelVersion: 2.6.27 Contact: linux-usb@vger.kernel.org Description: The latest IEs included in this device's beacon, in space separated hex octets with one IE per line.
What: /sys/class/uwb_rc/uwb//LQE 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.
What: /sys/class/uwb_rc/uwb//RSSI Date: July 2008 KernelVersion: 2.6.27 Contact: linux-usb@vger.kernel.org Description: Received Signal Strength Indication - the strength of the received signal in dB. LQE is a more useful measure of the radio link quality.
