Couple o' Mac questions
 

Does anyone know if the new 13" Macbooks two USB ports are on a single bus, or do they each have their own?

Also, I use a shareware program called USB Overdrive so that I can reprogram my multi-button mouse with specific commands per button per application (i.e. in Ableton Live I have a button that toggles full screen on and off and a button mapped to Undo). My question is: with a Bluetooth mouse, will it show up in USB Overdrive? That is, does the computer still pretend it's a USB device even though it's not?

Oooop...nevermind the bluetooth question. Should have checked his site first.
