persistent "Could not open device" error

[alex m.]

Ubuntu 12.04, Linux Mint 13:

freenect was installed via 1) Synaptic and 2) following the instructions found on http://openkinect.org/wiki/Getting_Started for Ubuntu/Debian

including 3) installation from the NeuroDebian repository.

In all these cases freenect-glview demo did not work giving the "Could not open device" error.

In the cases 1) and 2) gspca modules  gspca_kinect and gspca_main were removed before trying the demo.

The user belongs to the plugdev and video groups.

Kinect device is accessible using SimpleOpenNI Processing library under Mac OS X. Kinect's camera is accessible under Linux using GStreamer and Video4Linux.

lsusb lists 'Xbox NUI Camera', 'Xbox NUI Audio' + another line which has Microsoft Corp. in it. No 'Xbox NUI Motor'.

Any ideas why Kinect is not accessible using libfreenect and freenect-glview gives the "Could not open device" error?

I do not have USB 3.0 ports. 

The message I get after starting the glview demo is:

Kinect camera test
Number of devices found: 1
Could not open device

Did you just buy this Kinect?

Is it a K4W or an original model?

What model number is it?

this is Kinect for Xbox 360, Model # is 1473.

right. it looks like I have the same issue as this one: https://github.com/OpenKinect/libfreenect/issues/316

[Theodore Watson]

there is a very rough fix for it in the libfrenect files in this branch:

https://github.com/ofTheo/ofxKinect/tree/kinect-device-fix

just camera ( video/depth ) works. 

soon we should be able to get all the features working ( led / motor ) thanks to drew's recent email.

You tried sudo ?

[alex m.]

I did. Got the same error.

You tried sudo ?

You could try this fork https://github.com/renewagner/libfreenect/commits/k4w-wip Maybe it works

is there any progress in this? i ran into the same problem.
with the gspca_kinect modules i can acces both, the video and the sensor data.

is there the possibility to use a dummy driver for the motor?

i tryed to remove the motor routines from libfreenect, but then i got buffer mismatches...

[László Sátori]

I cant get it work! :(

I have made this things in libfreenect/build directory:

sudo make uninstall

make clean

then modified the src/cameras.c (line 907-909 "322 swapped to 334")

then in glview.c (line 415 "DEVICE_MOTOR removed")

after this, when i run glview:

Kinect camera test

Number of devices found: 1

GL thread

Szegmentálási hiba (core készült)

:(

what else can i do?

[László Sátori]

I did it! 

using this branch:

git clone git://github.com/renewagner/libfreenect.git

following this:

https://github.com/ofTheo/ofxKinect/compare/develop...kinect-device-fix

and the python wrapper works!

Thank you Renewagner and Theo!

Hi,all

I am new here. I got the same message as well

Kinect camera test
Number of devices found: 1

Could not open device.

The model number: 1414.
OS: Windows
libfreenect branch:unstable.

From the web search, my XBox kinect is an old version. It should be supported.

Regards
Jogging

Also got one to work using these changes.

@László - are you using a new Kinect for XBox, or a real Kinect for
windows. I have both an old and new Kinect for Xbox here (1414 and
1473). The code as written doesn't seem work for the new Kinect for
Xbox, because it only switches in the 334 byte expected return size if
it detected a Kinect for windows. This detection is done based on the
USB id. K4W is different, but both old and new models of K4Xbox have
the same USB ids. (Or maybe i misunderstood what you did) So
programmatically, the only way to tell is either noting the 334 byte
return, or the fact that the motor device is not present on the new
K4X.

In any case, i also got a Kinect for Xbox, model 1473 to spit out its
depth map simply by changing the expected size of the read msg to 334
bytes from 322. That change is the key change in the Theo link, in
camera.c above. All the other changes are just debug prints.

@Jogging: does lsusb show you the motor device? Thats the only way i
can tell the two models apart.

Caveat: - i have pretty limited experience with libfreenect (about an
hour), so im probably talking through my hat....

Thanks, Rupert.
In Device Manager, I install the drivers for three devices manually using the drivers coming with freenect.

Hi all,

I've had libfreenect working on Ubuntu 12.04 for a while now, well until Ubuntu did an update to some low level lib. Now it gets the same error for any Kinect I attach including version 1414, which should work fine. Has anybody else found this problem?

Hi Gang,

At one time, I had libfreenect working under Ubuntu 11.10. on my Pandaboard.  I just upgraded to 12.04, which I couldn't get to run on the board before, and now I get this same error.  I ran the modprobe commands talked about in the Ubuntu install instructions, to no avail.

All help is appreciated.

[Florian Echtler]

Hello rogermon,

which modprobe commands did your run? There are some problems regarding
USB 3.0 ports, but that shouldn't be an issue on the Pandaboard AFAIK.
Also, from which source did you install libfreenect?

Best, Florian
