Every PCI device on your computer has an ID that uniquely identifies its vendor, type, brand and model. If you are using PCI devices which were released in the same year or after the release of your Ubuntu distribution, you may want to update the PCI information on your system.
The update-pciids program can be used to update the PCI ID repository on your system. It just downloads the latest pci.ids file from here and stores it as /usr/share/misc/pci.ids
Remember to run the command as superuser:
$ sudo update-pciids
Tried with: Ubuntu 12.04.1 LTS
