Hello, Is usb3 vision camera supported in linux by uvc driver ? I did search but not sure that it is supported as part of uvc. I also founded usb3vision driver, but it does not seem a mainline driver (?) https://github.com/ni/usb3vision So, I am not sure what is the generic kernel driver that support usb3 vision. Thank you, Ran |

I'd definitely like to learn more about the state of UVC 1.5 in the kernel, what features depend on it (HDR?), and whether it's being worked on. Would be great if there was a bug report to follow along and help test if needed On Mon, Jan 29, 2018 at 4:18 AM, Walter <wal...@gm...> wrote: > Double check you are running native Linux not virtualized Linux.

I even had it with a c930e (not the resolution issue but being unable to directly extract the h.264 stream. It's come up here before: http://linux-uvc-devel. narkive.com/4XOCRkAM/logitech-c930e-h264-issue "I am trying to use Logitech c930e webcam with Linux environment. Unfortunately, H264 capability of the camera is not recognized by the kernel driver. My suspicion is that, This webcam is with UVC1.5 ; And, the linux kernel which ever I use are having the UVC driver version as 1.1.1; Even the latest 3.19 kernel ha this same version (1.1.1) uvcvideo layer needs an upgrade for detecting this ?" In the logitech forums as well: https://community.logitech.com/s/question/0D53100006aNKsvCAG/4k-brio- use-in-linux "I've been playing around with the BRIO and I noticed that when plugged into a USB 3.1 port and use v4l2-ctl you can see the camera's capability to produce 4k MJPEG. However I haven't been able to find a way to actually capture 4k (it looks to me like it tries to but times out resulting in a black screen in guvcview). With a little extra digging I discovered that the usb transfer rate is limited at 5000 Megabits when it should be 10000, but I still have no idea how to fix it." "Yep, I found that it works ONLY while using usb3, along with custom C code to capture the stream from the camera. Native support isn't there just yet." and https://community.logitech.com/s/question/0D53100006c8AjpCAE/uvc-15- support-on-linux |

Just for reference: is this camera working under Windows without any vendor related software installation? Try plug it into a "pure" Windows based machine where only the MS UVC drivers are installed and see what happen.

I bought a Pruveeo DV200 4k action cam, https://www.amazon.com/Waterproof-Camcorders-Accessories-Rechargeable-Batteries/dp/B072BBTYT5 The cam is cool, but, if I stick in the USB-Cable, it shows 3 options to choose: Take a Photo, Webcam and Recharge-Only Mode. If I choose Webcam, it jumps back to menu after two seconds. Maybe its a modeswitch-problem? If I take a look at /dev, for a second or two - when i cable it up - there is a /dev/video0 node, but it always disapear after two seconds. After that it mounts the SD-card. As you can see in the logs below, it says it found an uvc device. But the driver seems to release the device after creating a video-node. I'm new in this deep tec things in linux, but maybe YOU could tell me, if a few udev-rules must be made a custom way, or if this is a driver-problem, which can only fixed be the dev-ream ?!

I've had this problem across multiple devices, multiple versions of versions of Fedora, and am currently on kernel 4.14.15 Searching the web returns others with the same issues. I have never seen anyone with a solution to the issue or the ability to get additional streams to appear. This was my last place to turn, not my first. Is there a different command myself and others should be using instead that might reveal additional streams? Is UVC 1.5 irrelevant here?

Hello,
I'm wondering how to determine what prevents me from using my Logitech BRIO
with 4k resolution and an H.264 stream. Does this have to do with (lack of)
UVC 1.5 support, and is there a place to track UVC 1.5 support for linux?
Also, if donating my webcam to a developer would help, I would be happy to
do that. Currently, these are the streams that appear to be available:

Hi Lucas, First of all, thank you for your quick answer!! Unfortunately, it did not work...I will ask the company if there is a uvcdynctrl file or if they can tell me which extension units are supported. If it doesn't work, is there any way to figure that out using a software under Linux or under Windows (as the webcams are working under Windows).

These UVC GET_DEF errors could be causing a problem. Does your camera come with a uvcdynctrl xml file or datasheet that details the supported UVC extension units? The returned size appears to be wrong. Also, try the UVC_QUIRK_PROBE_DEF (0x00000100) quirk and see if that helps. >From http://www.ideasonboard.org/uvc/faq/ : UVC_QUIRK_PROBE_DEF: Don't request the video probe and commit default values.

Hello community, I have a webcam (in fact it is three webcams in one. One master with a master board and two that are linked to the master board). The webcam is working out of the box under Windows 10 but I cannot make it work under Linux (Fedora 26 kernel 4.14.14). I am using the same computer to do the tests, so I don't think that it is related to this. The three webcams are seen as different devices (/dev/video[1-3], /dev/video0 is the integrated webcam of my laptop). I followed the instructions given in the FAQ to gather information about the system. >From what I understand from the log, the cameras are detected correctly but I cannot figure out why it is not working. I tried a patch to the uvc driver following the stackoverflow post https://stackoverflow.com/questions/9781770/capturing-multiple-webcams-uvcvideo-with-opencv-on-linux/23881125#comment58189903_10353605 to add the fixed bandwidth quirks in MJPEG (which is the only format my cameras accept ) but it did not work... Can someone help me with this? How should I start? Thank you in advance for any help you could provide! 1- dmesg when I used guvcview on one of the three webcams.

I am attempting to set up a zoneminder system. I have numerous old thinkpads so I'm trying to use one or more of those. The problem is that Logitech cameras aren't playing ball. The frame rate is really low. My initial zoneminder system is a T410, i5 520 fresh debian 9.3 install. All ports report as USB 2. I have not installed X. Framerate is awful. USBmon reports a reliable 15270 +/- 50 kbaud. if I drop resolution to QVGA, that increases to ~22300kbaud. I have borrowed a c920 for troubleshooting, that manages about 13600kbaud. I also have a T410 running Lubuntu 16.04. USBmon reports the same speeds while using guvcview. A third T410 with Lubuntu 17.04 runs both cameras nicely in guvcview, even while grinding away at bitcoin core. I haven't installed USBmon on that one. I've tried swapping drives, the problem follows the drive. I've tried putting a usb wifi adaptor on the camera usb bus and dumping /dev/urandom from one PC to dev/null on the camera PC. This doesn't affect the USBmon reported camera bandwidth. I have one c615 and a borrowed c920 to get the system going. I have an Ausdom AW615 showing up in a week. I'm stuck, google isn't helping. I had trouble stopping the trace in the right place so it's two chunks of dmesg in one file. Attached files for the c615 and Debian 9.3 system. The Ubuntu 16.04 system seems to have the same problem. 17.04 merrily runs both cameras at 30fps at the same time if on different buses. I'll be using ~ 5fps for zoneminder. TIA -- They that can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety. ~Benjamin Franklin |

Hi Paulo and Laurent, I'm developing a UVC camera firmware with extension unit controls and would like to use V4L2_CTRL_TYPE_STRING and the corresponding UVC_CTRL_DATA_TYPE_RAW to get around the 4 byte limit of the other XU control types. Something similar to https://sourceforge.net/p/libwebcam/code/ci/master/tree/uvcdynctrl/data/046d/logitech.xml#l1630 : <mapping> <name>USB Information</name> <uvc> <control_ref idref="devinfo_usb_information_control_v1"/> <size>48</size> <offset>0</offset> <uvc_type>UVC_CTRL_DATA_TYPE_RAW</uvc_type> </uvc> <v4l2> <id>V4L2_CID_USB_INFO</id> <v4l2_type>V4L2_CTRL_TYPE_STRING</v4l2_type> </v4l2> </mapping> However, even though I rebuilt uvcdynctrl to support V4L2_CTRL_TYPE_STRING the uvcvideo driver appears to lack support for mapping this V4L2 data type. For example, uvc_v4l2.c:uvc_ioctl_ctrl_map() only supports V4L2_CTRL_TYPE_{INTEGER, BOOLEAN, BUTTON, MENU} ( http://elixir.free-electrons.com/linux/latest/source/drivers/media/usb/uvc/uvc_v4l2.c#L36 ). Is there a patch floating around that adds support that I can test? If not, I will try adding support since I have a device to test with. Either way any guidance would be appreciated. Thanks! |

Solved. Issue was as follows: Linux running within VirtualBox on OSX. VirtualBox only supports USB1.1 without Oracle VM VirtualBox Extension Pack. Once upgraded to USB2.0, everything worked fine. You might wish to review the following: 1. Upgrade to more helpful the nature of the error message(s) displayed by v4l2-ctl in case of "VIDIOC_STREAMON: failed: Input/output error". 2. Troubleshooting/FAQ entry to double-check USB version in use with device is 2.0+ 3. Highlight apparent common insufficient USB version/bus bandwidth limitation, symptom is unable to stream images but configuration may be seen/modified Hope that helps someone else! - Walter On 23 November 2017 at 09:11, Walter <wa...@pr...> wrote: > Precisely the same behavior observed (though able to query differing > camera capabilities) with a different model camera from the same > manufacturer, 058f:1412. > > - Walter > > On 22 November 2017 at 17:09, Walter <wa...@pr...> wrote: >> Please note the bandwidth quirk has been tested as described but no >> change was observed. >> >> Unsure if this is because the code was compiled in hard rather than as a module. >> >> - Walter >> >> On 22 November 2017 at 11:29, Walter <wa...@pr...> wrote: >>> New camera from Shenzhen. >>> >>> Camera is detected fine, driver loads with some errors, settings may >>> be queried and changed, however video or frame capture fails with >>> "VIDIOC_STREAMON: failed: Input/output error" and dmesg seems to >>> suggest some sort of bandwidth issue. >>> >>> Suggestions appreciated. >>> >>> Debug information attached. >>> >>> $ uname -a >>> Linux gentoo 4.12.12-gentoo #7 SMP Tue Nov 21 03:51:45 -00 2017 x86_64 >>> Intel(R) Core(TM) i7-4960HQ CPU @ 2.60GHz GenuineIntel GNU/Linux |

Precisely the same behavior observed (though able to query differing camera capabilities) with a different model camera from the same manufacturer, 058f:1412. - Walter On 22 November 2017 at 17:09, Walter <wa...@pr...> wrote: > Please note the bandwidth quirk has been tested as described but no > change was observed. > > Unsure if this is because the code was compiled in hard rather than as a module. > > - Walter > > On 22 November 2017 at 11:29, Walter <wa...@pr...> wrote: >> New camera from Shenzhen. >> >> Camera is detected fine, driver loads with some errors, settings may >> be queried and changed, however video or frame capture fails with >> "VIDIOC_STREAMON: failed: Input/output error" and dmesg seems to >> suggest some sort of bandwidth issue. >> >> Suggestions appreciated. >> >> Debug information attached. >> >> $ uname -a >> Linux gentoo 4.12.12-gentoo #7 SMP Tue Nov 21 03:51:45 -00 2017 x86_64 >> Intel(R) Core(TM) i7-4960HQ CPU @ 2.60GHz GenuineIntel GNU/Linux |

Please note the bandwidth quirk has been tested as described but no change was observed. Unsure if this is because the code was compiled in hard rather than as a module. - Walter On 22 November 2017 at 11:29, Walter <wa...@pr...> wrote: > New camera from Shenzhen. > > Camera is detected fine, driver loads with some errors, settings may > be queried and changed, however video or frame capture fails with > "VIDIOC_STREAMON: failed: Input/output error" and dmesg seems to > suggest some sort of bandwidth issue. > > Suggestions appreciated. > > Debug information attached. > > $ uname -a > Linux gentoo 4.12.12-gentoo #7 SMP Tue Nov 21 03:51:45 -00 2017 x86_64 > Intel(R) Core(TM) i7-4960HQ CPU @ 2.60GHz GenuineIntel GNU/Linux |

New camera from Shenzhen. Camera is detected fine, driver loads with some errors, settings may be queried and changed, however video or frame capture fails with "VIDIOC_STREAMON: failed: Input/output error" and dmesg seems to suggest some sort of bandwidth issue. Suggestions appreciated. Debug information attached. $ uname -a Linux gentoo 4.12.12-gentoo #7 SMP Tue Nov 21 03:51:45 -00 2017 x86_64 Intel(R) Core(TM) i7-4960HQ CPU @ 2.60GHz GenuineIntel GNU/Linux |

Hi there, I wanted to tell you that Logitech C920 camera is also fully working. But there is a problem with C930e which has no h264 on linux driver. Best regards, Vuk Vasić |

Hello,
I am trying to get a 5Mpixel usb camera from ELP to capture images. I
am getting corrupted images, only a few rows of good data followed by
nothing when capturing at 5M MJPEG. My goal is to capture at 5M YUYV
uncompressed. I can capture images from the camera at lower resolutions
in MJPEG. Also, I can capture 5M jpgs on my Windows box with this camera.
Tried guvcview, ffmpeg, but both crashed when trying to acquire an image
Capture command that does not crash, but has corrupted images:
>> fswebcam -S 2 -d /dev/video0 -p MJPEG -r 2592x1944 --save pic.jpg
I have also set:
>> modprobe uvcvideo quirks=642 nodrop=1 timeout=10000
I am running on a Beaglebone Black Industrial (Rev C) with latest Debian
image for it:
Linux beaglebone 4.9.45-ti-r57 #1 SMP PREEMPT Fri Aug 25 22:58:38 UTC 2017
armv71 GNU/Linux
Kernel traces attached.
Thanks in advance for any assistance

As a followup to yesterday’s email, I’ve discovered that I had improperly set the wMaxPacketSize in a couple of places which was causing issue # 2.
While I have also been reviewing the UVC spec again, I’m wondering if I am also going about this wrong. As mentioned before, the project currently has 2 unique VICs because I’d like to be able to stream both cameras simultaneously. I’m wondering if this really should designed as 1 VIC but with the following topology:
IT(1) -> PU(2) -> EU(3) -> OT(4)
IT(5) -> PU(6) -> EU(7) -> OT(8)
Does anyone know what approach is the proper method to take here?
Thanks again,
-Brian

Hi,
I'm currently developing a USB3 UVC peripheral which will feature 2 cameras as 2 discrete Video Interface Collections. I haven’t seen any similar products on the market, so in order to de-risk this effort I have started with a Cypress dev kit and I'm modifying their example project which loops a 2 frame video as “single camera” UVC compliant device. The initial demo project works fine, but with my firmware modifications I am encountering a handful of issues with uvcvideo on my Linux test machine (Ubuntu 17.04 / 4.10.0-35-generic).
The enumeration process and USB descriptors for my modified project appear to be fine when inspected with both my USB analyzer (Beagle USB 5000) and lsusb. I see both /dev/video0 and /dev/video1 but I run into issues once I try and access the streams (with VLC, gucvview, and the QTV4L2 test utility). All apps report variations of the error “no video device found”.
Digging into this a bit more, it appears that the host is not sending a GetDeviceStatus and GetInterfaceStatus when the feeds are accessed by the Host apps like I see with the single camera demo. I have turned on the uvcvideo trace and noticed the following peculiarities with the dmesg log.
During enumeration I get a dmesg error regarding the second camera and dbugfs. The exact error is “uvcvideo: Unable to create debugfs busnum-devnum directory.” This error obviously occurs because the busnum and devnum are the same for the 2nd camera, and debugfs was already created for the first camera.
The uvcvideo sequence is different between the two different firmware builds at the end of enumeration. With the single camera version of firmware I see the following sequence in dmesg:
[14332.280577] uvcvideo: UVC device initialized.
[14332.292304] uvcvideo: uvc_v4l2_open
[14332.292360] uvcvideo: uvc_v4l2_release
[14334.293725] uvcvideo: Suspending interface 1
[14334.293726] uvcvideo: Suspending interface 0
However, with the 2 camera firmware I see:
[14580.171459] uvcvideo: UVC device initialized.
[14580.183685] uvcvideo: uvc_v4l2_open
[14580.184600] uvcvideo: uvc_v4l2_open
[14582.186638] uvcvideo: Suspending interface 3
[14582.186639] uvcvideo: Suspending interface 2
[14582.186640] uvcvideo: Suspending interface 1
[14582.186641] uvcvideo: Suspending interface 0
Note that the device is never released.
Based on these findings, it looks like I’ll need to dive into the Linux uvcvideo source but I don’t have any experience in this source. Is there anyone on this list that might be able to tell me if I have overlooked some aspect of the UVC spec? Is it possible that I’m encountering issues that were overlooked since no multi-camera multi-feed devices exist? I know stereoscopic cameras do exist, but from what I have seen those devices have 1 VIC and only 1 stereo stream.
Thanks in advance,
Brian
