Hello, I would like to offer a patch for git://git.ideasonboard.org/uvc-gadget.git to avoid possible removal of event callback while the events dispatch loop is iterating through the available callbacks. Kind regards, - Dmitry Mikushin. |

Hello, While testing image streaming application available at git:// git.ideasonboard.org/uvc-gadget.git I've noticed the FPS setting supplied in the USB device config structures is not respected. In fact, gadget attempts the fastest possible frame rate. Moreover, the host tends to loose the pipe to UVC device due to probable low-level USB interface flooding due to opportunistic FPS selection. So, how can we set a hard-limit on FPS for UVC gadget? Thanks & Kind regards, - Dmitry. |

Hello, I am currently working on running two Logitech BRIOs on an Intel NUC. In the FAQ, under the question: I get a "No space left on device" (-28) error when trying to stream from more than one camera simultaneously. I see that one of the solutions is to test out a bandwidth number in: ``` /* Isochronous endpoint, select the alternate setting. */ bandwidth = stream->ctrl.dwMaxPayloadTransferSize; ``` However, I'm pretty new to this, so I was wondering whether you would outline how this can be done or point me to sources that can help me learn. I've tried the quirk method, but I still cannot get two cameras running, even at super low resolution (160x120). My guess is the webcam really requests much, much more bandwidth than it needs. -- Fasai Phuathavornskul Rice University Class of 2019 Electrical and Computer Engineering 1601 Rice Blvd. Houston, TX 77005 fp...@ri... 424-227-1996 |

Hello, I'm trying to use a FLIR Boson camera with UVC on my embedded platform (iMX6) but I can't make it work. I have made some troubleshoot and this is what I found: - The device is a Class video device, UVC driver recognises it - The driver finds 3 out of 4 formats, the last one is NV21, it have been given by the kernel log: Unknown video format 3132564e-0000-0010-8000-00aa00389b71. - When I start a gstreamer pipeline to get the video, gstreamer can't start the video (reason error (-5)) - I have a public gist where you can find all the logs (https://gist.github.com/Pehoh/39f4a8570d6c5299e6400dcaedd175fa) I have also tested the camera on my computer (Linux 4.15.0-43-generic #46~16.04.1-Ubuntu SMP Fri Dec 7 13:31:08 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux), and the gstreamer pipeline works fine. I still have kernel errors but I can see the video. You will find on another gist the logs on my Ubuntu (https://gist.github.com/Pehoh/1d1fe4901f6d7fd491fc01ab09e91429) This is what I have tried (with no success): - Adding the NV21 format in the driver, and link it to V4L2_PIX_FMT_NV21 - Forcing the format on the gstreamer caps (I tested NV12, NV21, I420, YU12, YV12) - Use a different driver code (more recent) for the embedded device Do you have any ideas? Regards, Pierre-Olivier |

Subject: [linux-uvc-devel] Reporting Device not on list 1b80:e607
Date: Tue, 29 Jan 2019 20:34:52 -0500
Appreciate any direction with this device and either identifying a
driver or whether building a driver using the v4l-dvb would be of any
benefit.
The device is labeled as an ADESSO AV-200.
Under Fedora 29
-a dmesg lists:
[ 646.652407] usb 1-3: New USB device
found,idVendor=1b80,Product=e607, bcdDevice= 1.00
[ 646.652409] usb 1-3: New USB device strings: Mfr=0, Product=1,

[ 646.652410] usb 1-3: SerialNumber: 11111111111111111111
a lsusb lists it as:
ID 1b80:e607 Afatech

Appreciate any direction with this device and either identifying a
driver or whether building a driver using the v4l-dvb would be of any
benefit.
The device is labeled as an ADESSO AV-200.
Under Fedora 29
-a dmesg lists:
[ 646.652407] usb 1-3: New USB device
found,idVendor=1b80,Product=e607, bcdDevice= 1.00

a lsusb lists it as:

The report of lsusb -v appears to dump something that resembles an

I have finally been able to get Cheese to recognize my webcam. Would any
information regarding my modules or whatnot be useful? I'm new to Linux and
have just been fumbling around to this point.

Problem has been resolved.
Tl;dr: ignoring the usb spec as far as cable length and voltage requirements is fine, cameras only work without usb extenders
Following the usb specifications on Wikipedia for usb max cable length is 16.5ft for usb2 and 9.8ft for usb1.1, with a line voltage in the range of 4.75-5.25v
As I need to locate the cameras 30-40ft away, I acquired some usb extenders which drop the bus down to usb1.1 (why 1.1 is still sold is beyond me) but that’s fine because now I can have longer wires while staying in the spec. using this at the end of the wire I had only 4.1v with the cameras powered up, so I then acquired a voltage booster to take that to 5.2v. now the system is in spec, but doesn’t work.
As a last ditch effort I simply cut the camera usb cord and extended it with 30 feet of cat6 ethernet: blue pair 0v, brwn pair 5v, green pair gnd, orange d+, orange stripe d-. works fine now even with 4.2v at the end, been running like this for 16 hours no glitches whereas with the standard-following setup it would run for max 100seconds.
It appears something in the kernel or drivers or whatnot breaks when working over usb1.1, im not sure this is even worth looking into a fix for since 1.1 devices are obsolete aside from this specific usb extender.
Thanks all for your help.

USB 1.1 will be a limiting factor for your application. A 160x120 YUYV frame is 38400 bytes in size. The camera sends only 944 bytes in one USB frame (1ms interval). So the camera needs 41 USB frames to transfer one video frame. So at 15fps, one camera needs 41*15=615 USB frames to transfer data. So when you use two cameras, you will not have enough bandwidth and will end up dropping data.
Still, it is not reason enough for the device to get disconnected. The log does not show what causes the camera to disconnect. You might want to enable logs in the USB host controller driver to debug the problem.

In the log file, it appears that the cameras are getting identified as
full speed devices and not as high speed devices. Are you running out
of bandwidth when trying to capture from both cameras?

Evening,
I'm trying to run two Logitech c270 webcams at the same time on a raspberry pi3. Running one by itself as a continuous video stream works fine, attempting to open two at the same time never works.
I'm doing this in python via pygame, to eliminate any possible issues on my code I manually ran the commands in idle and wrote down the times to compare them with the kern.log file after enabling the trace as explained in the FAQ. I attached the log file during the time I was running the commands, following are the commands and their corresponding line number in the log file as well as the time they were ran(based on log file time)
LOG FILE LINE UPTIME COMMAND
pygame.camera.init()
143 260.14 pygame.camera.list_cameras()
cam0 = pygame.camera.Camera('/dev/video0')
157 356.70 cam0.start()
cam1 = pygame.camera.Camera('/dev/video1')
260 372.23 cam1.start()
793 501.14 cam0.stop()
Cam1.stop() # fails, bad file descriptor
It appears from the log cam1 attempts to start but the driver drops it, then the camera remounts as /dev/video2, subsequent attempts to reconfigure and start the camera as video2,3,4 etc has the same effect.
The only way to access cam1 is to stop cam0 first, but each time a camera is stopped it is released then remounts as something else, eventually failing after a few minutes of start/stop/remount cycles.
I've attempted to apply the 0x80 quirks as recommended in https://elinux.org/RPi_USB_Webcams but that lead to an I/O error when cam0.start() was ran.

I am trying to use a UVC Microscope on Lubuntu 16.04.4. It has worked a few times, but without changing anything in the system it will fail on a subsequent try. I have been unable to establish why it does work sometimes. Once it fails it continues to fail after multiple power down and reboots. I have tried using the microscope on other machines, changing USB socket, re-installing guvcview, resetting cheese settings using dconf-editor. Sometimes it will work after doing some of these things, but there is nothing repeatable. After a failed attempt to use the microscope, Lubuntu cannot shutdown and I have to switch off the power. Using cheese the microscope gives a black screen the first times it fails. Subsequent attempts cause cheese to say no video device is found. I have attached log files from dmesg and lsusb. The microscope does work on another Lubuntu machine. The hardware is totally different and it is running a slightly older version of OS (Lubuntu 16.04.02). Help would be appreciated. |

Hello devs, I have a dual boot Fedora 28/Windows 7. The camera works fine with Windows, but it does not always work with Fedora. I used the trick to "rmmod/modprobe uvcvideo" for the past few Fedora releases, but it is not working anymore. The camera seem to work after (both Fedora 28 and few past releases): 1. any upgrade of the mesa* libraries (always); 2. rebooting into Fedora after having used the Windows partition (most times). Any hints ? Thank you. |

I have a low cost webcam that worked out of the box with Mint 18.3. Now, after upgrade to Mint 19, there is no /dev/video0 device. I have tried the cam with windows and it's ok. I have tried with a second Mint 18.3 PC and it's ok. I have also tried with a live-CD Mint 19 and it fails. The command to obtain the lsusb.log file, gave me a warning: lsusb -d 1410:1410 -v > lsusb.log Couldn't open device, some information will be missing No warnings without the "> lsusb.log" part. |

Hi Karl, Have you tried updating to a newer version of the Kernel ? I had the same issue on a HP EliteBook 840 G5, with a similar Chicony Electronics camera, and support was added in kernel 4.17.4.

Hi everyone, I have a 04f2:b569 Chicony Electronics Co., Ltd built-in camera in my Lenovo Laptop. I see externally plugged-in camera's work fine but not the built-in one. Do you know if this device is supported, I cannot find it on your Supported Device ID list. Thanks |

I can have at most two cameras connected at once running the following with `ffmpeg`. I am using Logitech C920's. As soon as I start to use 3 cameras it doesn't work (the no space left on device error). I have tried `quirks=128` (and it just hangs after that) and have similar issues here: - https://askubuntu.com/questions/1003741/no-space- left-on-device-issue-in-using-multiple-cameras <https://askubuntu.com/questions/1003741/no-space-left-on-device-issue-in-using-multiple-cameras> - https://superuser.com/questions/431759/using- multiple-usb-webcams-in-linux - https://stackoverflow.com/questions/45257954/ubuntu- camera-vidioc-streamon-error-28-no-space-left-on-device <https://stackoverflow.com/questions/45257954/ubuntu-camera-vidioc-streamon-error-28-no-space-left-on-device> - https://stackoverflow.com/questions/11394712/libv4l2- error-turning-on-stream-no-space-left-on-device <https://stackoverflow.com/questions/11394712/libv4l2-error-turning-on-stream-no-space-left-on-device> |

Hi,
I have problem with usb webcam,with id 5149:13d3 on BeagleBoneBlack with
"Linux arm 4.17.6-armv7-x7".
I Can try to acquire a photo frame with opencv with python and v4l using a
C programming,
I am sure that this code and webcam work's, because i tryed it with another
board and I haven' t this problem.
After some research i find a solution, i load uvcvideo with these
parameters :
"modprobe uvcvideo nodrop=1 timeout=5000 quirks=0x30"
I have tryed to change quirks but doesn't works.
This is code for python:
>>>import cv2
>>> cam=cv2.VideoCapture(-1)
>>> suc,frmae=cam.read()
>>> cv2.imwrite("testubuntu1.jpg",frmae)
>>> cam.release()
The c code is https://github.com/arembedded/usb_cam
Regards

Hi Robert, Thanks a lot for your answer, that really gives hope for the future. I hope the 4.17(.4) kernel will make it to Stretch backports quickly then. There one thing that confuses me now: the devicelist* doesn't contain my device (04f2:b5e7) while your message suggests the driver that's included in the 4.17.4 kernel will have support for the device I have. How does that work? A good weekend everyone! *) http://www.ideasonboard.org/uvc/#devices Best regards, Alex > From: "Robert Sandor" <san...@gm...> > To: "Alexander Swen" <ale...@sw...> > Cc: "linux-uvc-devel" <lin...@li...> > Sent: Friday, 20 July, 2018 15:48:17 > Subject: Re: [linux-uvc-devel] Request for support of Chicony webcams in HP > Elitebook G5 laptops > Hi Alexander, > I had the same issue running the HP Elitebook 840 G5 with Ubuntu. > The issue has been solved in the Linux Kernel version 4.17.4, so installing that > should enable the webcam. > Best, > Robert > On Fri, Jul 20, 2018 at 3:28 PM Alexander Swen via Linux-uvc-devel < > lin...@li... > wrote: >> Hi, >> I hope I follow all your guidelines for posting in this list as this is my first >> post here and I couldn't find much documentation about how to file a request. >> If I do something wrong I hope you forgive me and still want to help me. >> I recently received a new laptop to do my work on.

Hi Alexander, I had the same issue running the HP Elitebook 840 G5 with Ubuntu. The issue has been solved in the Linux Kernel version 4.17.4, so installing that should enable the webcam.
