Sonnet Technologies has announced
a FireWire/USB Express/34 card for Windows notebook computers that will also be compatible with MacBooks when Mac OS X v10.5 “Leopard” ships in October. It costs $69.95.
The FWUSB2-E34 card offers one USB 2.0 and two FireWire 400 ports and can support multiple peripherals at the same time. It works in both ExpressCard/34 and ExpressCard/54 slots — only the ExpressCard/34 interface is found on MacBook Pros, however.
