Icron's WiRanger USB hub looks like a normal USB hub except for the wireless antenna that connects it to the USB receiver which hooks into your PC. So we suppose it doesn't really look like a normal USB hub after all. Unlike other wireless USB solutions, the WiRanger uses 802.11g, but in all other respects it behaves just a normal hub. That means all your standard USB gadgets will work just like in a standard hub.
What's the point? Mostly to hook up a USB printer or some various low-bandwidth devices at a distance. But hooking up a USB hard disk over its 802.11g may not deliver the kind of performance anyone would like.
