Happily, no.

Well, all _PCI_ devices (including mini-PCI ones).  ;->  It's nothing
more or less than the result of asking the PCI controller chip "What'cha
got?"  In olden days, you'd also run pnpdump (for ISA Plug and Play
devices -- which of course would not register non-PNP stuff).  These
days, you also query lsusb, if you want to get somewhat close to "all
devices".

Skim-reading "dmesg | more" is also often useful.
