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