its about WUSB, basically wireless USB. It might be compatable with normal USB devices, I'm not sure. Reading it though, i found this
'The Wireless USB Promoter Group is chartered with defining the wireless USB (WUSB) specification. Already there has been some progress with the definition of a WUSB specification with a targeted bandwidth of 480 Mbps. This specification maintains the same usage and architecture as wired USB with a high-speed host-to-device connection. With these considerations in place, it will enable an easy migration path for today's wired USB solutions.'
This suggests that it uses the same form of technology as USB2, so maybe they will use an adapter for this technology.
No idea when its out though, you'll ahve to do some research
