Linux: Determine the Manufacturer of a PCI Device

How do I determine the manufacturer of a PCI device under Linux operating systems?

To find out or determine the manufacturer of a PCI device from Linux operating system, use the lspci command. Open a command-line terminal (select Applications > Accessories > Terminal), and then type the following command:
$ lspci
