Malcome "I want to test the Bluetooth to DSLR function first"
Nice, I've not had any success in getting from Bluetooth back to USB at the device end.
I'm currently having a Play with a Belkin Homebase unit
http://www.belkin.com/au/IWCatProduc...duct_Id=508689. It has a built in 4 port hub and can be run via ethernet cable or Wifi to a router.
- My Canon 550d works well via Backyard EOS and the EOS utility want's to start up.
- I've been able to connect a 7 port hub to it and connect devices connected to the Hub (the Hub does not show as a device)
- Bluetooth modules have not registered yet.
- I can connect to an Arduino (USB to serial) but attempts to fire up the Arduino software have so far caused a blue screen

No hassles when the USB is plugged into the PC directly.
- A generic webcam does not seem to register. I've not yet tried a Philips webcam or others with more specific drivers.
- A generic Gamepad seems to connect fine.
Adding a new device (or turning off the Canon and then back on) seems to disconnect other devices.
If I can get everything I need working that way it might also meet a lot of what I'm trying to achieve. Bandwidth across Wifi should be far better than USB.
So far I'd say it's flakier than I'm happy with but has some promise.
