/etc/udev/rules.d/90-kinect2.rules
<code>
# ATTR{product}=="Kinect2"
SUBSYSTEM=="usb", ATTR{idVendor}=="045e", ATTR{idProduct}=="02c4", MODE="0666"
SUBSYSTEM=="usb", ATTR{idVendor}=="045e", ATTR{idProduct}=="02d8", MODE="0666"
SUBSYSTEM=="usb", ATTR{idVendor}=="045e", ATTR{idProduct}=="02d9", MODE="0666"
</code>

<code bash>
sudo udevadm control --reload
</code>

On Ubuntu avoid autosuspend of USB. Add usbcore.autosuspend=-1 to grub options
<code bash>
# check with
grep . /sys/bus/usb/devices/*/power/autosuspend
</code>

To connect kinect I have to use proper USB 3.0 chipset like [[http://www.amazon.it/dp/B00NLD15VQ/ref=sr_ph?ie=UTF8&qid=1430917762&sr=1&keywords=usb+3.0+pci|this]]

===== OpenCL =====

<code bash>
sudo apt-get install beignet beignet-dev opencl-headers

===== libfreenect2 for CUDA =====

  * [[http://jetsonhacks.com/2015/02/23/kinect-v2-with-libfreenect2/|...leggi]]

<code bash>
git clone https://github.com/xlz/libfreenect2.git
sudo apt-get install -y build-essential libturbojpeg libtool autoconf libudev-dev cmake mesa-common-dev freeglut3-dev libxrandr-dev doxygen libxi-dev libjpeg-turbo8-dev
cd libfreenect2/depends
cp -r $path_of_gstjpeg_src/nv_headers .
sh install_ubuntu.sh
sudo ln -s /usr/lib/arm-linux-gnueabihf/libturbojpeg.so.0.0.0 /usr/lib/arm-linux-gnueabihf/libturbojpeg.so
cd ../examples/protonect/
mkdir build && cd build
cmake ..
make
../bin/Protonect
</code>


MAX_ISO_BUFFER_LENGTH in usbfs.h caused issues. In the published version, the size is 49152 * 128, the mPCIe card/Jetson didn't like that, but works when the size is **49152**.
===== libfreenect2 =====

<code bash>
cd /lab/kinect
sudo apt-get install -y build-essential libturbojpeg libtool autoconf libudev-dev cmake \
  freeglut3-dev libxrandr-dev doxygen libxi-dev libopencv-dev
sudo ln -s /usr/lib/x86_64-linux-gnu/libturbojpeg.so.0 /usr/lib/x86_64-linux-gnu/libturbojpeg.so
git clone https://github.com/OpenKinect/libfreenect2

cd libfreenect2/depends
./install_ubuntu.sh
cd ../examples/protonect
cmake  -DENABLE_CXX11=ON
make && sudo make install
</code>

Patch to avoid black screen
<code>
For example in Protonect.cpp:

add an include after line 37

#include <libfreenect2/packet_pipeline.h>

change line 61 from

libfreenect2::Freenect2Device *dev = freenect2.openDefaultDevice();

to

libfreenect2::Freenect2Device *dev = freenect2.openDefaultDevice(new libfreenect2::CpuPacketPipeline());
