-Usage: $progname COMMAND DEVICEs [ARGS]
-
-Command for manipulating the pairing/authentication credentials of a
-Wireless USB device that supports wired-mode Cable-Based-Association.
-
-Works in conjunction with the wusb-cba.ko driver from http://linuxuwb.org.
-
-
-DEVICE
-
- sysfs path to the device to authenticate; for example, both this
- guys are the same:
-
- /sys/devices/pci0000:00/0000:00:1d.7/usb1/1-4/1-4.4/1-4.4:1.1
- /sys/bus/usb/drivers/wusb-cbaf/1-4.4:1.1
-
-COMMAND/ARGS are
-
- start
-
- Start a WUSB host controller (by setting up a CHID)
-
- set-chid DEVICE HOST-CHID HOST-BANDGROUP HOST-NAME
-
- Sets host information in the device; after this you can call the
- get-cdid to see how does this device report itself to us.
-
- get-cdid DEVICE
-
- Get the device ID associated to the HOST-CHID we sent with
- 'set-chid'. We might not know about it.
-
- set-cc DEVICE
-
- If we allow the device to connect, set a random new CDID and CK
- (connection key). Device saves them for the next time it wants to
- connect wireless. We save them for that next time also so we can
- authenticate the device (when we see the CDID he uses to id
- itself) and the CK to crypto talk to it.
-
-CHID is always 16 hex bytes in 'XX YY ZZ...' form
-BANDGROUP is almost always 0001
-
-Examples:
-
- You can default most arguments to '' to get a sane value:
-
- $ $progname set-chid '' '' '' "My host name"
-
- A full sequence:
-
- $ $progname set-chid '' '' '' "My host name"
- $ $progname get-cdid ''
- $ $progname set-cc ''
-
-EOF
