1) PCI 2.1 refers to what version of the peripheral connect interface (PCI) standard the card works with. This number can describe a motherboard, audio cards, video cards, network cards, SCSI cards, FireWire cards, and so on. It tells you nothing about USB.
2) Unless the card packaging specifically says it's USB 2.0, you can bet it's USB 1.1. And, last I looked, there weren't any CompUSA branded USB 2.0 cards. 3) Even if it were a USB 2.0 card, there are no USB 2.0 drivers (extensions) for "classic" MacOS (OS 9.x and earlier). To take advantage of 2.0, you need to run OS X. 4) All USB 2.0 cards and devices are supposed* to fall back to 1.1 if one or the other is less than 2.0. So, in principle, you could use a 2.0 CD burner, but it wouldn't run at full speed. *In practice, some USB 2.0 cards don't work at all in PCI Macs.
