This is a port/adaptation of Hector Martin's libfreenect for OS X made by Theodore Watson.
Hector Martin's Libfreenect project page is here:
Most of the code is unchanged but there are some changes to libusb which was needed to get it running ( and a few extra libusb commands ) as well as some tweaking of the transfer sizes.
It should be self contained and you shouldn't need to install libusb ( the app links it directly ).
Grab the Source Code:
( Tested on OS X 10.6.3 - 32bit now and with fixes )
ofxKinect for OF users - thanks Dan!
- Try both usb ports.
- Try not to have too many other devices plugged in ( or any ).
