Combined hardware identification databases
==========================================

This repository contain a specially re-packaged copy of the pci.ids
and usb.ids files, as well as a copy of IEEE's databases for the
Organizationally Unique Identifiers (OUI) and Individual Address Block
(IAB).

The two IDs databases are maintained by Martin Mares and Michal Vaner
(pci.ids) and Stephen J. Gowdy (usb.ids) through the help of
volunteers who can submit them to the two submission web applications:

 * [pci.ids](http://pci-ids.ucw.cz/)
 * [usb.ids](https://usb-ids.gowdy.us/index.html)

The OUI and IAB databases are two officially maintained indexes by
IEEE, and can be accessed at:

 * [OUI](http://standards.ieee.org/develop/regauth/oui/public.html)
 * [IAB](http://standards.ieee.org/develop/regauth/iab/public.html)

The reason to repackage the files together is to make it simpler for
applications to require them, without having to bring in either
pciutils or usbutils, that might be unnecessary for most installs.

Updates
-------

The hwids tarball is updated generally on the weekends, and tagged if
there are new files available. You can download the tags in form of
tarballs directly from [the GitHub
repository](https://github.com/gentoo/hwids).

udev
----

Since version 196 and later, `udev` does not consume the hwid files
directly. Instead, it only access a specific binary representation,
which is further generated starting from intermediate representations.

The Makefile will accept a `UDEV=yes` parameter to build and install
these representations. Furthermore upon install, the binary
representation will also be generated.

License
-------

The pci.ids and usb.ids files are both released under dual-license,
and you can choose which one to apply to your needs. The options are
either the GNU General Public License, version 2 or later (which
you'll find in the archive, in the file named gpl-2.0.txt), or the
3-clause BSD license that follows:

The IEEE datafiles for OUI and IAB assignments are provided by the
IEEE without an explicit license, but are considered in all effect as
public domain, as they are simple representation of factual
information, which would then fail the threshold of originality test.
