| it probably can, but Firewire has all of the stuff in place. but then
| again so do USB CD-R's
USB CD-R/W is a SCSI hack. That is, the driver and drive pretent to be
SCSI devices. USB was never intended to be used for this sort of thing.
It is a low speed bus, like Apple's ADB, intended for keyboards, mice,
tablets, sticks, possibly modems, printers, and other low-bandwidth
devices. Using it for "fast" devices like disks and scanners and network
adaptors was not intended but is allowed for. 4x-6x is the absolute
maximum that USB CD-R/W can maintain, and that is if the writer is the only
thing on the bus. Even a mouse on the same bus can drop that to 1x-2x,
assuming it can keep up at all.
IEEE 1394 was designed from the ground up to be a cheap, fast bus for high
speed data transfer, primarilly disk I/O, with the intention for multimedia
applications like digital audio and video recorders.
USB 1.1's absolute maximum throughput of 11Mbps vs IEEE 1394's current
400Mbps.
