GSPCA webcam no longer working: no /dev/video0

[Warren Butler]

I am running Intrepid amd64 and plug in an Intel webcam, documented to be support by the gspca driver. This camera worked on a Hardy installation on the same machine.

The device appears to be properly detected and the gspca driver loaded.

However, it cannot be accessed by any applications.

Error returned when running gstreamer-properties:
Video for Linux (v4l): Device "/dev/video0" does not exist.

Description: Ubuntu intrepid (development branch)
Release: 8.10

[Leann Ogasawara (leannogasawara)]

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test:

1) If you are comfortable installing packages on your own, the linux-image-2.6.27-* package is currently available for you to install and test.

--or--

2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback.

[Warren Butler (grumpymole)]

Problem still exists with 2.6.27.

It appears that the module is correctly loaded, but that /dev/video0 is not created. This is causing the problem.

I also had my webcam working on Hardy, but the same cam on same machine is not working in Intrepid.

I can not get the cam working with any of the app, cheese or skype. I get no error while running cheese or skype, but don't get he video.

Ubuntu Intrepid Ibex (with kernel 2.6.27-7.14-generic)

Camera (D'Link DSB C320 - pixart chip (pac7311)) work only in Chease or Ekiga (without recording video) but have very poor image quality (colour saturation flashing with very poor image resolution) that make it unusable.
In Chease captured images don't have colour and saturation artefacts but have poor resolution (mixed noise?)
Sound from camera (internal microphone) don't work.
TVtime say "frames too short from pac7311" in displayed blue screen.
if I'm trying record video in Chease - Chease hangs or record no more then one second of video with huge memory (RAM) consumption.
In Windows XP camera works well.

I guess, the duplicate status of this bug is wrong. It starts with a report, that /dev/videoX is not created when plugging a "gspca"-webcam. This is also my problem, running Ubuntu 8.10 with a 2.6.27-8-generic kernel and an "Aiptek Minicam", which is recognized as a "Sunplus Technology Co., Ltd SPCA504a Digital Camera". (The other comments complain about problems with some applications, but most of the reporters HAD a /dev/video on their machine!)

Reffering to the drivers, I had no problems in hardy and earlier versions of Ubuntu using the "gspca" module. The /dev/video0 file was created and I could use the device with "ekiga" and lately "cheese".

So me and the reporter of the initial bugreport have a problem with the driver (gspca_XXX), not with a library (libv4l) as in #260918.

Some further informations about my webcam/camera:

Ubuntu uses the "gspca_sunplus" driver with my device. "gspca_main" and "videodev" is also loaded. An icon is also placed on the desktop - I guess it's for the photo- and not for the webcam-function. ;)
Interesting detail: I've got the "Platten einbinden"-applet (I don't know, how it is originally called. It is for mounting and unmounting devices, I guess it's called the "drivemount-applet") and the Aiptek-Cam is ALWAYS shown TWICE, with one of them mounted and the other unmounted. If I try to mount the unmounted twin, the applet crashes and must be reloaded. Maybe this all has something to do with the strange message "gspca: disconnect complete" or with the uncreated /dev/video0 device...?

I have a similar problem with a Logitech ClickSmart 310 camera, supported by gspca (spca500), which used to work without problems in Hardy. Here is the dmesg output when plugging it in:

No /dev/video is created, and hence no application finds the camera. The camera is found by lsusb:

Bus 005 Device 003: ID 046d:0900 Logitech, Inc. ClickSmart 310

I installed the libv4l packages as per bug 260918, but I don't think that's relevant because the error is at the point of mounting the camera. Any progress on the issue? Any workarounds? (Again, the camera worked without problems in Hardy, I don't know what caused the regression and there are no workarounds that I know of yet).

I have the same problem with Mustek gSmart 300 in Jaunty RC. Mustek gSmart 300 is basically a webcam that was made to look as a digital camera, has a very small inbuilt memory enough for taking 20-30 pictures of 640x480. But the webcam functionality is the main reason people bought it. When the webcam is pluged-in it shows almost the same behavior as described in bug report #291906 (Mustek gSmart 300 not working in Ubuntu 8.10) which was marked as duplicate of bug #285682 (Ubuntu 8.10 can't mount digital camera showing a window popup message: -60 could not lock the device message). This time there is no window popup message: -60 but there are 3 beeps. The end result is that the camera is properly detected, but no /dev/video0 is created. We can see this from

dmesg
...

[59707.327245] gspca: probing 055f:c200
[59708.523532] gspca: disconnect complete

As you can see the device is probed twice, and after the second probing there is some kind of disconnect.

lsmod | grep gspca gives
gspca_spca500 21632 0
gspca_main 29952 1 gspca_spca500
videodev 41600 1 gspca_main

I found a temporary solution by removing gspca modules from the memory and then installing them again by:

sudo rmmod gspca_spca500
sudo rmmod gspca_main
sudo modprobe gspca_spca500

After this is done, there are no multiple beeps, and dmesg gives:
...

This time /dev/video0 is properly created and the webcam works under skype. It has other problems under cheese, kopete, vlc etc. which I presume are related to other kind of bugs.

The second temporary solution I found was to kill /usr/lib/gvfs/gvfs-gphoto2-volume-monitor process before pluging the webcam into the computer. I didn't post my comment under bug #285682 because the discussion over there is mostly related to digital cameras and not webcams and secondly because there was a heated discussion and someone stating that this is completly normal and this is how things should be, resulting in bug #285682 status marked as invalid . Please don't forget that Mustek gSmart 300 is basically a webcam with a very low sensor resolution. Can this kind of "multifunctional" webcams be blacklisted from the gvfs or gphoto2 modules?

I have the same problem: in Jaunty the Creative PC-CAM 600 webcam does not work anymore. This is a fresh Jaunty installation. The webcam was working in a previous release such Feisty so the bug is a regression.

At each connect I get this message:

abramo kernel: [ 3031.407320] usb 2-1: USB disconnect, address 9
abramo kernel: [ 3042.244054] usb 2-1: new full speed USB device using ohci_hcd and address 10

I need to reload the gspca_sunplus module manully each time I connect the webcam:

sudo modprobe -r gspca_sunplus
sudo modprobe gspca_sunplus

in order to have the correct creation of /dev/video0. The log message while unloading/reloading the module is:

After the module reloading the webcam works well with Cheese and xawtv. However with skype and ekiga the image quality in very poor (dark) at a level that I can hardly distinguish any shape.

I'll be happy to provide any further information.

[Mitsch (kontakt-riotmusic)]

Tried my webcam in karmic - still no success!
The modules ("gspca-sunplus", "gspca-main" and "videodev") are loaded, but still no /dev/video* device to make "cheese" and other apps working with my webcam. In /var/log/messages nothing happens when I plug in the camera, so I added the messages of "sudo udevadmin monitor":

The mass-storage-part of that device is - by the way - no more recognized. I can't mount it. The good news about it is that I no longer get an error message from nautilus on every start up... :) I got this behaviour since intrepid. So, no change for me in jaunty and karmic.

Conclusion: Ubuntu recognizes the device correctly, all modules are loaded - but there is no /dev/video. Is it possible to try a mknod by hand? If yes, what are the correct options (major and minor numbers) to do it? Maybe, it's the missing thing to do to get a working webcam... O.k. - maybe not, but it's worth a try! :)

Greetings!

[Mitsch (kontakt-riotmusic)]

Got a good hint in #440590:
The modules must be reloaded after boottime to work correctly:

modprobe -r gspca-sunplus
modprobe gscpa-sunplus

That does the trick for me! A /dev/videoX is created, accessable and full functioning!
I hadn't success putting these lines in rc.local - it won't be executed. Still have to figure out, why. But if I execute the two lines by hand after every boot, I have my webcam back, again!

[Mircea Postolache (mircea273)]

Make sure rc.local is executable and use full path on the things you want to run e.g. /sbin/modprobe ...

Got it working.
The problem was not, that rc.local wasn't executed, but the modprobe trick seems to work only, if booting is finished. My rc.local now looks like this:

modprobe -r gspca_sunplus && sleep 60s && modprobe gspca_sunplus
exit 0

Now, everything works.

[Antonio (tritemio)]

Following from comment #20. I have the exact same behaviour as described in #20 in karmic too (fresh installation). The syslog is the same too. To summarize:

1. Creative PC-600 webam does not work out of the box anymore in jaunty and karmic
2. The module unload-reload trick works (must be redone each time the webcam is connected)
3. Skype gives almost black (unusable) video (worked before jaunty).

Followup to #31:

After seeing the 'gspca: disconnect complete' line in dmesg, I executed the following:

sudo rmmod gspca_spca500
sudo rmmod gspca_main
sudo modprobe gspca_spca500

And the following appeared in dmesg:

[604283.194613] usbcore: deregistering interface driver spca500
[604283.194694] spca500: deregistered

At that point, I have a /dev/video0, and cheese can see it and use it. Skype, however, requires the following to work properly:

export LD_PRELOAD=/usr/lib32/libv4l/v4l1compat.so && skype

I'm also seeing a great number of these types of errors in dmesg after the camera is active:

but at least the workaround seems to work OK for me.

[Heather Van Wilde (heatheriac)]

Oh, thank you, thank you, thank you ... i had the same errors as you did, but this command does work for me:

sudo rmmod gspca_spca500
sudo rmmod gspca_main
sudo modprobe gspca_spca500

after plugging in the camera ... got the same dmesg output. haven't tries skype yet though

[Heather Van Wilde (heatheriac)]

oh, and on another note, it appears the commands need to be run every time you plug in the camera (and likely everyime you turn on the computer)

[skywriter (xxxiter)]

After plugging camera i got the following from "dmesg":

[61670.227091] gspca: probing 055f:c520
[61670.617116] gspca: probe ok
[61670.617195] gspca: probing 055f:c520
[61670.746256] gspca: disconnect complete

This looks similiar to comment #19 but instead of "gspca_spca500" I got "gspca_sunplus" in result of "lsmod" command. I healed this by replacing the module gspca_sunplus with gspca_spca500 this way:

sudo modprobe -r gspca_sunplus
sudo modprobe -r gspca_main
sudo modprobe gspca_spca500

Now i get the following from dmesg:

[63545.151603] Linux video capture interface: v2.00

[63545.160261] spca500: registered

Seems OK, but I still have no "/dev/video0". How to get back it to live?
Is there any manual way? This webcam worked OK in ALT Linux 4.0 Desktop.

I seems gspca driver is a part of kernel now so there is no sense in compiling old drivers from mxhaard:

Sorry, I forgot to mention that I always run Skype with "export LD_PRELOAD=/usr/lib32/libv4l/v4l1compat.so && skype" workaround. Otherwise webcam does not work.

Upgraded the kernel from 2.6.32 to 2.6.35. Problem still the same. But for workaround to work I need remove one more module: sudo rmmod gspca_spca561
