USB was announced in OS 8.1 with the iMac. It wasn't supported on other Macs until 8.5.
I'm pretty sure he's asking about the PCI version... not the USB version. AFAIK, all Macs w/ PCI slots are PCI 2.1 compliant. Some macs (notably the pre-AGP G4 - yikes mobo, i think) have non-spec PCI slots (66MHz or 64bits wide) to support faster video cards, but these are still compatible w/ PCI 2.1 As for USB 2.0, you are right: it is backward compatible w/ USB 1.x devices - you can plug in that USB keyboard, printer, modem, etc to that USB 2.0 port w/ no worries. Currently, only OrangeMicro makes USB 2.0 cards for Mac. They are not supported in the OS by Apple - you need extensions from Orange for the cards to work.
