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.

KernelVersion: 2.6.27
Contact: David Vrabel <[email protected]>
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.
