Hello everyone!
I'll be sending out periodic status updates to make it easy to track the progress of this effort. Here is the latest status!
Opening words
WOW! I'm really amazed at the response from the community about open source Kinect drivers and the possibilities of what we can do with them.
For those who don't know me, I started this group and have taken on the role of project lead. I knew there was going to be people hacking away at Kinect, it only makes sense to combine efforts (especially now that the divise competition is over!) I expected maybe a handful of people to join this mailing list and maybe make some progress towards one or two pet projects. I never expected this many people, and this is great! I've got a little bit of news for you guys:
I just approved a set of applications which put of over the edge of 400+ members! Actually we have 405 members, and I'm sure that by the time I'm done with this there will be more people asking to join. I loved reading the little blurbs you write about yourselves, and we automatically approve anyone who tells us about themselves. The diversity in this group is amazing. Developers. Artists. Robiticists. Doctoral candidates. Professors. Interaction designers. Game designers. And that is just browsing the last 50 or so people who joined. With this group of motivated people I know we can accomplish great things!
Software status
So let me get you up-to-date on the actual software effort. We have now successfully combined the three different codebases that individuals had been working on after the USB dumps were posted and while this group was organizing. The main source repository is at:
All developers should be using this repo as the base for development efforts.
Working right now in this repository are drivers and extremely bare-bones sample application for Linux and OS X. We are currently working hard on the Windows version as well and plan to support all three platforms. We will also have managed wrappers for .NET development.
Licensing
I've been discussing with the contributing developers so far and we've also come to an agreement on the licensing. The products of this group will be available under two licenses. Users can choose to use this project under the terms of Apache 2.0 or GPL v2. In non-lawyer speak, that means that you can use this project almost any way you want. You can even modify it and combine it with proprietary code (with Apache 2.0) or use it with other GPL code. This maximizes the reach of the project, which I think is appropriate considering the amazing innovative ways to use it that you guys will come up with.
Project information
Now that the code bases are merged and getting organized, I've also written up the first bit of information about this project and group on the OpenKinect Wiki. I'd encourage everyone to take a look and browse some of the pages especially under Project Information. I'll just point out that the RoadMap page is probably of interest to everyone.
I'll continue to send periodic updates so you can track the project status. Most of the developers hang out on IRC in #OpenKinect on freenode.net as well so you can drop by and see what is going on in real-time.
As we progress on the driver and software side, we'll figure out ways to enable more of you to contribute to the project, even those who do not code. See this page for some ideas.
Discussion and a new announcement-only list
Please feel free to discuss (as some of you are already) ideas about how to use Kinect or technical topics about the software on this list. If this list gets too much email traffic for your taste, please join the OpenKinect-Announce list here:
There is no application and only project administrators can post. We'll only post status updates every few days so it will be low traffic, perfect for if you want to keep tabs on our progress but not get too much email.
I'm inspired by you guys. The community is coming together and making this happen. Big thanks to ceupcat for helping me click approve a few hundred times, and marcan, qDot, ofTheo, and Majority for the work so far on the code.
Thanks,
Josh
P.S. I was right -- we're now up to 407 members.

Hi ! ( GitHub Page currently doesnt work, so i post here )
Have tried to add to the c # opensource projekt a camera class.
Besides, I have read in "inits.txt" file from c projekt and did send
the inits to the camera. Everything wonderfully runs, camera works.
The only problem, besides: libusbdotnet library obviously supports no
async usb callback. Tried everything, always win32error... Any clue or
other idea which usb-library to use in c#?
here the code switching on the camera :
public struct caminit
{
public byte[] init;
public caminit(byte[] initArray)
{
init = initArray;
}
};
/// <summary>
/// sends the inits read from "inits.txt" (file taken from c
project)
/// </summary>
public void SendInits()
{
// init_send ??
UsbSetupPacket setup = new UsbSetupPacket(0x80, 0x06,
0x3ee, 0x0, 0x12);
int len = 0;
byte[] buf = new byte[18];
MyUsbDevice.ControlTransfer(ref setup, buf,
(ushort)buf.Length, out len);
// send the inits list
buf = new byte[0x2000];
foreach (caminit ci in inits)
{
setup = new UsbSetupPacket(0x40, 0x0, 0x0, 0x0,
(ushort)ci.init.Length);
MyUsbDevice.ControlTransfer(ref setup, ci.init,
(ushort)ci.init.Length, out len);
setup = new UsbSetupPacket(0xc0, 0x0, 0x0, 0x0,
0x200);
len = 0;
while (len == 0)
MyUsbDevice.ControlTransfer(ref setup, buf,
(ushort)buf.Length, out len);
// TODO : test of response buffer
}
}
private static void ReadInitsFile()
{
// get new inits list
inits = new List<caminit>();
// open the file
StreamReader sr = new StreamReader("inits.txt");
// Read in the data in a list
List<string> list = new List<string>();
string l;
while ((l = sr.ReadLine()) != null)
list.Add(l); // Add to list.
sr.Close();
// loop throug the file lines
foreach (string line in list)
{
// continue if empty or not out commented
if (line == "") continue;
if (line[0] == '#') continue;
// split the line, continue if not 4 parts
(cmd,tag,cdata,rdata)
string[] split = line.Split(',');
if (split.Length != 4) continue;
// get command and tag
Int16 command = Convert.ToInt16(split[0], 16);
Int16 tag = Convert.ToInt16(split[1], 16);
// get the commands and the lenght count ( in UINT16
len count )
Int16 len = 0;
Int16[] cmddata = new Int16[1024];
for (int i = 0; i < split[2].Length / 4; i++)
{
len++;
cmddata[i] = Convert.ToInt16(split[2].Substring(i
* 4, 4), 16);
}
// create init command buffer, first two bytes "magic"
bytes
byte[] init = new byte[8 + (len * 2)];
init[0] = 0x47;
init[1] = 0x4d;
// set the data in the init buffer, first two bytes
empty, then len, command, tag, then the commanddata
byte[] bytes = BitConverter.GetBytes(len);
init[2] = bytes[0]; init[3] = bytes[1];
bytes = BitConverter.GetBytes(command);
init[4] = bytes[0]; init[5] = bytes[1];
bytes = BitConverter.GetBytes(tag);
init[6] = bytes[0]; init[7] = bytes[1];
for (Int16 i = 0; i < len; i++)
{

Hi,
When I was hacking at getting the isochronous requests working in libusbdotnet earlier last week I also was getting errors, not sure if they're the same as yours.
Either way, the plan is to have libfreenect be the drivers and API for getting raw data out of the hardware. This is being written in C and is crossplatform to support Windows, Linux, and OS X. We will have managed wrappers on the API to access it in .NET.
I'd recommend holding off on working on the C# project until we get the drivers and API complete. Of course if you want to mess with it just because, feel free.

Github had a database issue, still restoring from backup. Need to re-rename the repository.
