lspci dumps all devices found on all pcibusses, and is a crucial tool if you're
trying to figure out why no driver seems to want to attach to a certain
PCI device. You can get some of that functionality from a dmesg if you look
carefully, but lspci is more descriptive and more verbose (And it doesn't
require wading through a dmesg)

It's part of sysutils/pciutils.
