Expect to find speedy USB ports on most PCs, peripherals by 2004

The Universal Serial Bus port will soon be ubiquitous on PCs and peripherals, according to Cahners In-Stat Group of Newton, Mass.

One or more USB ports now come standard on new PCs, and the market research group predicted there will be 750 million USB-equipped desktop and notebook PCs in use by 2004.

Video cameras and scanners are the peripherals most likely to have USB ports today. But the hot-swap interface is gaining ground in printers, monitors, keyboards, mice, modems, hubs, external storage drives and other peripherals.

In-Stat analyst Robyn Bergeron said the 12-Mbps USB 1.1 specification is substantially faster than parallel, serial and PS/2 ports.

USB 2.0 devices arriving late this year will operate about 40 times faster than current USB devices'up to 480 Mbps, Bergeron said.

The 2.0 specification will support multiple devices such as digital speakers and high-resolution videoconferencing cameras and will have throughput comparable with that of the 400-Mbps FireWire 2.5 bus. CD-recordable and rewritable and hard drives are among the peripherals that will have FireWire interfaces.
