3.1.5: uvcvideo: Failed to resubmit video URB (-27).

Hello,

Using an Acer 7551-7442 here with the following built-in webcam:
Bus 002 Device 004: ID 0402:9665 ALi Corp. Gateway Webcam

It seems motion locks up every day or so and I see this in the kernel logs:
[378982.724053] uvcvideo: Failed to resubmit video URB (-27).
[378982.724066] uvcvideo: Failed to resubmit video URB (-27).
[378982.724079] uvcvideo: Failed to resubmit video URB (-27).
[378982.724090] uvcvideo: Failed to resubmit video URB (-27).
[378982.724101] uvcvideo: Failed to resubmit video URB (-27).
[489148.723367] uvcvideo: Failed to resubmit video URB (-27).
[489148.723379] uvcvideo: Failed to resubmit video URB (-27).
[489148.723391] uvcvideo: Failed to resubmit video URB (-27).
[489148.723403] uvcvideo: Failed to resubmit video URB (-27).
[489148.723414] uvcvideo: Failed to resubmit video URB (-27).

If I restart motion, it will usually start working again, I do not
have this problem on other (retail) Logitech webcams, was curious if
this a bug with the webcam (quirk?) or a problem in uvcvideo?

The camera is built-into the laptop screen at the top in the middle.

What should I do if I want to add new control through the uvcdynctrl

Hi, all:

I'm a newer of Linux developer, and I'm interesting in the UVC EU because I want to add my personal control for the camera(for example, zoom in/out, which the camera supports).
what I have done is as follow:
(1) Get the GUID of the device;
(2) Modify the "usr/share/uvcdynctrl/data/

046d/logitech.xml", and replace the GUID with the new GUID, VID, PID;
(3) And I load the XML dynamically with the command "uvcdynctrl"

But it returns the error that: Unable to add control with GUID...

So I'm wondering that is there any examples about how to add new control for the device?
If no, what's the meaning of tag "selector", "index","size", where is the value comes from?

<control id="logitech_video_raw_bpp">
<entity>UVC_GUID_LOGITECH_VIDEO_PIPE</entity>
<selector>XU_RAW_DATA_BITS_PER_PIXEL</selector>
<index>7</index>
<size>1</size>

If there is an example about how to add the new control, I will very appreciate for that!!
Thanks for your attention!

Re: Philips SPZ2000/00

Hi,

Just a little comment to clarify a point maybe unknown:

Actually Skype for Linux (I am talking about Skype v2.2 Beta) does support MJPEG video ;)

"In the Linux client, you must either use YUV or MJPEG.  NV12 is not supported.  To use MJPEG with the Linux client an external library is required to convert the video data for Skype.
 
From the README file:
* If your camera capture is showing a green, scrambled or black image,
this workaround may help:
- Ubuntu 32 bit: install "libv4l-0" package and launch Skype with: 
LD_PRELOAD=/usr/lib/libv4l/v4l2convert.so skype
- Ubuntu 64 bit: install "lib32v4l-0" package and launch Skype with: 
LD_PRELOAD=/usr/lib32/libv4l/v4l2convert.so skype
- Other distributions might have the same library, but may have a 
different path."

Best Regards,

Marco.

With the debug message you send i can see following jpeg 172x144 <at> 30fps set 512 B/frame jpeg 320x240 <at> 30fps set 768 B/frame - in this case we get error -28 ENOSPC No space left on device. The bandwidth provided by this cam seems to be really wrong. My logitech set for bot jpeg 172x144 <at> 30fps and 320x240 <at> 30fps 192 B/frame. How about raw? do it request wrong bandwidth for raw to? Currently i do not know how to handle the freeze issue. So here is the list of problems by this cam: - - it is not USB 2.0, this is why we can request bigger resolution - - it cant handle resolution switch on the fly, and in case of URB error, we need to hard reset it. If we will try to reset the cam with uvcvideo we will kill audio stream (for cam with build in mic). This will make other people angry and add unexpected bug. - - it provide wrong bandwidth info. I still ask my self, how windows handle this? or is there some undocumented agreement between factories and microsoft? -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk7TYZQACgkQw8E0jNwoJm9XUgCgiwNK2VFdvfEJwxV/1fdTsCya 3BwAn2KwsLEhAiROhOmzPXs6I85lot7q =BhM4 -----END PGP SIGNATURE-----

AVEO Technology Corp. 1871:0516

Hello

I got a USB-microscope from Aldi supermarket. When I attach it to my
computer with Ubuntu 11.10, the following is written to syslog. After
that, there is the output from lsusb. I expect it will use the
uvcvideo-module, because other AVEO Technology Corp. microscope do, but
I don't know for sure. Please let me know if you need more info.

information on Logitech Quickcam Pro 9000 for Business

Hi; i've the necessity to use this webcam for videoconferencing because it has  a wide-angle lens.
So in your list this is the problem 6 that says:


At least some versions of this camera severely overexpose images when the manual exposure control is set to a value other than 2500 divided by an exponent of 2. Auto-exposure isn't affected.

This webcam works well audio/video if the exposure is set automatically? it is controlled by adobe flash plugins.

Thank's

Hue HD resolution problems

Hi,

I've got a Hue HD webcam (device ID 0c45:62f1) that I'd love to get
working fully under linux. UVC driver picks it up fine when plugged in,
but only allows up to 640x480 capture. This is in exactly as predicted
by the supported devices note (11), which says that "Those cameras claim
to have a true 1.3MP or 2MP CMOS sensor, but the highest resolution
reported by the UVC descriptors is 640x480".

Does anyone know if there is a way to persuade the driver to accept
higher resolution, slower capture from this device? My understanding is
that 640x480 resolution isn't intrinsic to all cameras on UVC driver. If
it's not possible, then that would be useful information too, but I'd
happily have a go at patching the driver if someone could point me in
the right direction.

The camera works at 1600x1200 (10fps) on Windows. lsusb.log below. dmesg.log is pretty long because of
many "uvcvideo: Dropping payload (out of sync).", so just selected highlights below.

Thanks for any help you can offer,
Bill

[ANNOUNCE] Mailing list move to SourceForge

Hi everybody,

Berlios will unfortunately close on December the 31st. I have thus decided to 
move the linux-uvc-devel to SourceForge.

I've filed a support request with SourceForge to mass-subscribe the existing 
mailing list members to the new list, while retaining the digest option (other 
option may be lost, sorry for the inconvenience). You will likely receive an 
e-mail to inform you of your subscription to the new list in the near future.

You can already visit https://lists.sourceforge.net/lists/listinfo/linux-uvc-
devel for information about the new list. Please keep using the Berlios list 
for now. I will disable it after receiving the mass subscription confirmation, 
and ask SourceForge to import the list archives.

Webcam/mic device 046d:082b Logitec c170

Hello to the team,

I have just bought a new webcam with microphone 
  Logitec c170
  with IDs 046d:082b
which is not in the list of the page www.ideasonboard.org/uvc/#devices

It seems that both the camera and the microphone work, as I've managed
to use them with pidgin. Is there any other test that you want me to run
in order to confirm that it works ok in all aspects?
(like checking resolution(s) with some v4l program, or checking
suspending, etc.)
Do you want me to send you any usb dumps/logs or anything?

Acer HD Crystal Eye webcam

Hello together,

I've got the Acer Aspire 5930 and my problem is that my webcam doesn't
work anymore. I've seen that the cam is a supported device (064e:a117),
so I decided to write to you.
Two years ago, under ubuntu 8.10, the webcam just worked, but in later
versions of ubuntu (ubuntu 9.04, 9.10, 10.04, 10.10), I didn't get a
/dev/video0 device.
I'd really appreciate any hints.

Regards, Lucien
