Hi Tim,
Thanks for the feedback. The question is not one of having benefit.
Here's the question: Today I bought a mouse that has a usb-bt dongle
in the box. Say I'm a naive user. I put it on my computer, not
knowing anything.
What's going to happen? Actually I'm going to find out soon, because
I'm going to try it!

Daniel,
I don't expect there would be any benefit of having more than one
Bluetooth interface active, it may make things worse as they may
interfere with each other. I say that on the basis that all
Bluetooth comms occur in the same frequency band, with frequency
hopping used to help reduce collisions between independent devices.
The only benefit I could see is when the devices are different
classes, e.g. using a class 1 device for services which need
greater range, but a lower power one for short range things like
keyboard and mouse. This would be a conscientious way to reduce
your interference impact on your neighbours.
Tim.

Can a mac have more than one bluetooth device? I tried plugging in a
dongle, and I believe what happened was that the dongle replaced the
builtin bluetooth device.
Also the api for finding out info about the bluetooth device seems to
only support one device. Is there a definitive answer?
