There are some ABI documents that, while they don't generate any warnings, they have issues when parsed by get_abi.pl script on its output result. Address them, in order to provide a clean output.

Description:
|
|
Various files for managing Cable Based Association of
|
|
(wireless) USB devices.
|
|
|
|
The sequence of operations should be:
|
|
|
|
1. Device is plugged in.
|
|
|
|
2. The connection manager (CM) sees a device with CBA capability.
|
|
(the wusb_chid etc. files in /sys/devices/blah/OURDEVICE).
|
|
|
|
3. The CM writes the host name, supported band groups,
|
|
and the CHID (host ID) into the wusb_host_name,
|
|
wusb_host_band_groups and wusb_chid files. These
|
|
get sent to the device and the CDID (if any) for
|
|
this host is requested.
|
|
|
|
4. The CM can verify that the device's supported band
|
|
groups (wusb_device_band_groups) are compatible
|
|
with the host.
|
|
|
|
5. The CM reads the wusb_cdid file.
|
|
|
|
6. The CM looks it up its database.
|
|
|
|
- If it has a matching CHID,CDID entry, the device
|
|
has been authorized before and nothing further
|
|
needs to be done.
|
|
|
|
- If the CDID is zero (or the CM doesn't find a
|
|
matching CDID in its database), the device is
|
|
assumed to be not known. The CM may associate
|
|
the host with device by: writing a randomly
|
|
generated CDID to wusb_cdid and then a random CK
|
|
to wusb_ck (this uploads the new CC to the
|
|
device).
|
|
|
|
CMD may choose to prompt the user before
|
|
associating with a new device.
|
|
|
|
7. Device is unplugged.
