Keyspan Inc. is shipping its Hi-Speed USB 2.0 4-port Hub. They’ll work with Macs that have a USB connection, although only at USB 1.1 speeds.
You can buy the hubs in a variety of colors at a manufacturers suggested retail price of US$59. Each one comes with a USB 2.0 device cable and power adapter. To date, Apple hasn’t announced their plans, if any, for USB 2.0 support.
In addition to the new USB 2.0 Hubs, Keyspan offers a line of PCI and CardBus cards that let users upgrade Macs or PCs with USB 2.0 connectors. The company also offers a PCI card that provides both USB 2.0 and FireWire ports.
