Source Of The pci.ids file
Content comes from a website: https://pci-ids.ucw.cz/ (mirror https://github.com/pciutils/pciids )
it looks like the file may be located in different directories on different Linux OSes (pci.ids file location is different on Ubuntu and Fedora).
Correct but why does that matter? You use a command/tool to update and probe for vendor ids so the system will find it itself.
- Debian base systems use pci.ids and
/usr/share/misc/pci.ids - Others can also use hwdata and
/usr/share/hwdata/pci.ids
