Kinect v.2 on Mac - Device connection failure
Hello! I just got a hold of a Kinect v.2 and I'm trying out Shiffman article on the subject: http://shiffman.net/p5/kinect/
I'v copy pasted this code now just to see if the connections are ok, but I am getting an error that I am unsure of. I am currently on an MacBook Pro 2011 that doesn't have USB 3, but I can still connect USB 3 devices on it. Could this be related to that?

It seems that the Kinect is recognised ok, but I still get: ... [UsbControl::claimInterfaces(IrInterfaceId)] failed! libusb error -3: LIBUSB_ERROR_ACCESS ... no device connected or failure opening the default one!
Just need help narrowing down my search as I don't have any other hardware to test it on. Is it just the USB3 problem?
Thanks, Franck :)
Answers
I would think it was a USB3 issue:
FAQ: Can I use the Kinect v2 without an USB3 port? No. It's a pure USB3 device due to the high bandwidth requirements.
