These errors are not permissions-related.\r\nNote that **freenect-regview** does function correctly.\r\nWhat actually bothers me is that, for an unknown reason, I am unable to run the [OpenCV example](http://openkinect.org/wiki/C%2B%2BOpenCvExample) on the Raspberry Pi 2, it returns the same error codes and messages (*-4, could not open motor and audio*).\r\nThe thing is, I do not actually care for motor and audio, only video and depth.\r\nI have been able to run the OpenCV example on an Ubuntu 14.04 laptop, but I have no idea why it does not run on the Raspberry Pi 2 (I have already followed these steps and also asked for help [here](http://www.mariolukas.de/2015/04/proof-of-concept-3d-scanner-with-kinect-and-raspberry-pi2/)). I have been running the latest version of both Raspbian and Arch Linux, with no success other than **freenect-regview**.\r\nA strange thing that happens is, whenever I run a freenect application, the following message appears in **dmesg**, and I don't know whether it is a feature or a bug:\r\n> [ 9513.700007] usb 2-1.1.1: reset high-speed USB device number 76 using ehci-pci\r\n> [ 9518.790646] usb 2-1.1.1: can't restore configuration #1 (error=-110)\r\n> [ 9518.791096] usb 2-1.1.1: USB disconnect, device number 76\r\n> [ 9518.878488] usb 2-1.1.1: new high-speed USB device number 77 using ehci-pci\r\n> [ 9524.428664] usb 2-1.1.1: new high-speed USB device number 78 using ehci-pci\r\n> [ 9524.523389] usb 2-1.1.1: New USB device found, idVendor=045e, idProduct=02be\r\n> [ 9524.523399] usb 2-1.1.1: New USB device strings: Mfr=1, Product=2, SerialNumber=3\r\n> [ 9524.523406] usb 2-1.1.1: Product: Microsoft Kinect Audio, \\xffffffc2\\xffffffa9\\xffffffa9 2011 Microsoft Corporation.
