-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.
