What is this command? Is this command useful? Do I need to update my pci?

$ sudo update-pciids

This command will update a file /usr/share/pci.ids which contains information which numerical vendor and product IDs have which name. This database is only needed if you want not only numerical IDs when executing "lspci" or similar commands but also some text describing the device. E.g. on my laptop I have a "Intel Wireless WiFi Link 5100", but the hardware only reports an ID 8086:4232 and the pci.ids are used by lspci to map this ID to the name. But for a device to work properly it is not necessary to have an updated pci.ids file.

So it is not necessary to update the pci ids.
