WUSB command line script to manipulate auth credentials¶
#! /bin/bash
#
set -e
progname=$(basename $0)
function help
{
cat <<EOF
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
}
# Defaults
# FIXME: CHID should come from a database :), band group from the host

Special thanks to:
Inaky Perez Gonzalez <inaky@peloncho.fis.ucm.es> for starting the
Linux USB driver effort and writing much of the larger uusbd driver.
Much has been learned from that effort.
The NetBSD & FreeBSD USB developers. For being on the Linux USB list
and offering suggestions and sharing implementation experiences.
Additional thanks to the following companies and people for donations
of hardware, support, time and development (this is from the original
THANKS file in Inaky's driver):
The following corporations have helped us in the development
of Linux USB / UUSBD:
- 3Com GmbH for donating a ISDN Pro TA and supporting me
in technical questions and with test equipment. I'd never
expect such a great help.
- USAR Systems provided us with one of their excellent USB
Evaluation Kits. It allows us to test the Linux-USB driver
for compliance with the latest USB specification. USAR
Systems recognized the importance of an up-to-date open
Operating System and supports this project with
Hardware. Thanks!.
- Thanks to Intel Corporation for their precious help.
- We teamed up with Cherry to make Linux the first OS with
built-in USB support. Cherry is one of the biggest keyboard
makers in the world.
- CMD Technology, Inc. sponsored us kindly donating a CSA-6700
PCI-to-USB Controller Board to test the OHCI implementation.
- Due to their support to us, Keytronic can be sure that they
will sell keyboards to some of the 3 million (at least)
Linux users.
- Many thanks to ing büro h doran [http://www.ibhdoran.com]!
It was almost impossible to get a PC backplate USB connector
for the motherboard here at Europe (mine, home-made, was
quite lousy :). Now I know where to acquire nice USB stuff!
- Genius Germany donated a USB mouse to test the mouse boot
protocol. They've also donated a F-23 digital joystick and a
NetMouse Pro. Thanks!
- AVM GmbH Berlin is supporting the development of the Linux
USB driver for the AVM ISDN Controller B1 USB. AVM is a
leading manufacturer for active and passive ISDN Controllers
and CAPI 2.0-based software. The active design of the AVM B1
is open for all OS platforms, including Linux.
- Thanks to Y-E Data, Inc. for donating their FlashBuster-U
USB Floppy Disk Drive, so we could test the bulk transfer
code.
- Many thanks to Logitech for contributing a three axis USB
mouse.
Logitech designs, manufactures and markets
Human Interface Devices, having a long history and
experience in making devices such as keyboards, mice,
trackballs, cameras, loudspeakers and control devices for
gaming and professional use.
Being a recognized vendor and seller for all these devices,
they have donated USB mice, a joystick and a scanner, as a
way to acknowledge the importance of Linux and to allow
Logitech customers to enjoy support in their favorite
operating systems and all Linux users to use Logitech and
other USB hardware.
Logitech is official sponsor of the Linux Conference on
Feb. 11th 1999 in Vienna, where we'll will present the
current state of the Linux USB effort.
- CATC has provided means to uncover dark corners of the UHCI
inner workings with a USB Inspector.
- Thanks to Entrega for providing PCI to USB cards, hubs and
converter products for development.
- Thanks to ConnectTech for providing a WhiteHEAT usb to
serial converter, and the documentation for the device to
allow a driver to be written.
- Thanks to ADMtek for providing Pegasus and Pegasus II
evaluation boards, specs and valuable advices during
the driver development.
And thanks go to (hey! in no particular order :)
- Oren Tirosh <orenti@hishome.net>, for standing so patiently
all my doubts'bout USB and giving lots of cool ideas.
- Jochen Karrer <karrer@wpfd25.physik.uni-wuerzburg.de>, for
pointing out mortal bugs and giving advice.
- Edmund Humemberger <ed@atnet.at>, for it's great work on
public relationships and general management stuff for the
Linux-USB effort.
- Alberto Menegazzi <flash@flash.iol.it> is starting the
documentation for the UUSBD. Go for it!
- Ric Klaren <ia_ric@cs.utwente.nl> for doing nice
introductory documents (competing with Alberto's :).
- Christian Groessler <cpg@aladdin.de>, for it's help on those
itchy bits ... :)
- Paul MacKerras for polishing OHCI and pushing me harder for
the iMac support, giving improvements and enhancements.
- Fernando Herrera <fherrera@eurielec.etsit.upm.es> has taken
charge of composing, maintaining and feeding the
long-awaited, unique and marvelous UUSBD FAQ! Tadaaaa!!!
- Rasca Gmelch <thron@gmx.de> has revived the raw driver and
pointed bugs, as well as started the uusbd-utils package.
- Peter Dettori <dettori@ozy.dec.com> is uncovering bugs like
crazy, as well as making cool suggestions, great :)
- All the Free Software and Linux community, the FSF & the GNU
project, the MIT X consortium, the TeX people ... everyone!
You know who you are!
- Big thanks to Richard Stallman for creating Emacs!
- The people at the linux-usb mailing list, for reading so
many messages :) Ok, no more kidding; for all your advises!
- All the people at the USB Implementors Forum for their
help and assistance.
- Nathan Myers <ncm@cantrip.org>, for his advice! (hope you
liked Cibeles' party).
- Linus Torvalds, for starting, developing and managing Linux.
- Mike Smith, Craig Keithley, Thierry Giron and Janet Schank
for convincing me USB Standard hubs are not that standard
and that's good to allow for vendor specific quirks on the
standard hub driver.
