I have a USB product that I'd like to use wirelessly on my Mac Mini media center. Is there a product that connects via Bluetooth to the computer and acts as a USB hub?
I'm afraid the bandwidth of Bluetooth is not sufficient for USB devices, even for USB 1.1 devices.
From this page:
There are wireless USB hubs (like this one) but they do not rely on Bluetooth for communication. I haven't used one (they're still pretty expensive) so I'd suggest you search for "wireless USB hub" on your favorite search engine for models and reviews.
