Failed to set the LED of K4W or 1473 device: LIBUSB_ERROR_IO

[duckduckhero]

please help me i am very urgent

i am trying to connect my kinect 1517 to ubuntu 18.04

i downloaded libfreenect and everything, and if i try to execute freenect-glview
i keep getting this error.

freenect-glview Kinect camera test Number of devices found: 1 Found sibling device [same parent] Failed to set the LED of K4W or 1473 device: LIBUSB_ERROR_IO Found sibling device [same parent] Could not open device: LIBUSB_ERROR_NO_DEVICE Could not open device
maybe it's because of the usb problem?
because i don't have any usb bus 003 when i execute lsusb -t

anyways please help me
i searched everywhere, but i wasn't able to find the answer...
please help me..

I have this problem too. Do you have any answers?

I have this problem as well:

Failed to set the LED of K4W or 1473 device: LIBUSB_ERROR_IO
Found sibling device [same parent]
Could not open device: LIBUSB_ERROR_IO

[peproctor]

Mine works after trying this solution from another answer (#543):

"Please try freenect-camtest, which uses only the camera.
The root cause is probably missing audio firmware. Model 1473 uses the audio device to control the motor, and needs firmware for the audio. I am working on a firmware fix, but I still can't get it to work with 1473. In the meantime, I'm thinking of printing out warnings when audio/motor fails to load instead of stopping the program"

So, Can't we open Kinect 1473 through OpenCV?
Is there any other way rather than this? (for Model 1473)

Me too!

What did it for me, was running freenect-micview and freenect-camtest before freenect-glview.

This worked for me! thanks a lot!

What did it for me, was running freenect-micview and freenect-camtest before freenect-glview.

When I run freenect-micview I get:

Number of devices found: 1

any help is appreciated.

The file audios.bin is missing (I'm not sure but I think it is a firmware that needs to be sent to to the kinect during runtime)
To download it, go to the git cloned folder of libfreenect and run:

python3 ./src/fwfetcher.py

This will download the audio.bin to the libfreenect folder, then simply move it to the location of the installed libfreenect library

sudo mv ./audios.bin /usr/local/share/libfreenect/

@n-qber,

This worked for me! thanks a lot!

I have also the model 1473 (I did not know where to get this info: it's depicted in the sticker on the foot of the device) and I had the same error LED of K4W or 1473 device: LIBUSB_ERROR_IO with, i.e., freenect-glview . I solved the case by the following two steps depicted in #543:

• what @frederico-klein said: python3 ./src/fwfetcher.py
• then what @StoneLabs said: comment the line fnusb_keep_alive_led(ctx, audio); in usb_libusb10.c

  libfreenect/src/usb_libusb10.c

  Line 443 in aca6046

  fnusb_keep_alive_led(ctx, audio);

EDIT: today I wanted to retry tests but I got this error similar to #650:

Trying to open ./audios.bin as firmware...
Trying to open ~/.libfreenect/audios.bin as firmware...
Trying to open /usr/local/share/libfreenect/audios.bin as firmware...
Trying to open /usr/share/libfreenect/audios.bin as firmware...
Trying to open ./../Resources/audios.bin as firmware...
upload_firmware: failed to find firmware file.
upload_firmware failed: -2
Could not open device

I tried to call back python3 ./src/fwfetcher.py but I get stalled with:

Downloading SystemUpdate.zip from https://www.xbox.com/system-update-usb
Reading response...

I did not understood but my hypothesis is that I shall be libfreenect/build once in this folder it runs back well

[Lecrapouille]

Update. On my Ubuntu I got this error again. This is because I was inside the build folder. After doing sudo make install and cd .. it worked back

If anyone is still checking this thread... I am attempting to run python3 ./src/fwfetcher.py to download the audio file audio.bin but it seems that https://www.xbox.com/system-update-usb is no longer a page on the Xbox website (error 404).

Would anyone know where I can manually download the files or update.zip that fwfetcher.py used to download from the website? Or if someone has the files I can download from them? Much appreciated!!
