i've tried connecting two windows kinects to a macbook pro running windows 7 64 bit, and no problems, everything worked has expected
when i try to do the same on a desktop computer (running windows 7 also), i get erratic behavior on kinect 2. sometimes it disappears, other times i only get kinect 1 available. I watched the device manager and the erratic behavior also shows there, with an exclamation point showing up sometimes over the icon of one of the kinect cameras.
i suppose the problem is connected to the usb root hub that the desktop computer is using to route the USB ports, so i will try to get my hands on a pci -> usb 2.0 card, and see if it goes away
anyone tried this?
