Logitech Quickcam E2500 not supported

Bug Description

I recent bought the Logitech Quickcam E2500, which is budget webcam. It is not supported under Ubuntu 8.10 (AMD64). The fix is trivial, and the risk is essentially zero. So I propose that the patch is applied as an update.

The patch is already applied upstream:
http://<email address hidden>/msg02282.html

lsusb says:
Bus 001 Device 004: ID 046d:089d Logitech, Inc.

and uname -a:
Linux mythtv 2.6.27-11-generic #1 SMP Fri Feb 6 15:47:26 GMT 2009 x86_64 GNU/Linux
(this is my modified version, with the patch)

There is a related bug, but it is concerned with the old (V4L1 ?) driver: https://bugs.launchpad.net/ubuntu/+source/gspca/+bug/273727 .

confirming. The camera is still not working in jaunty.

And I can confirm that the fix (adding "{USB_DEVICE(0x046d, 0x089d), .driver_info = SENSOR_MC501CB}," to gspca/zc3xx.c) still applies and it indeed pops up working correctly with Ekiga. The fix is indeed entirely trivial and it would be cool if it could be supported in Jaunty.

Hi Guys,

Sorry for not seeing this earlier. I think this was most recently reassigned to the correct "linux (Ubuntu)" package in launchpad. I'm pasting the upstream git commit id below for the kernel team to reference. Unfortunately the kernel is currently frozen in preparation for the upcoming Jaunty release. However, this indeed seems to be a trivial patch with a pretty low (or rather no) risk of introducing any regression. I'll approve the Jaunty nomination and ping the kernel team to try to get this in as a stable release update post release. I the meantime as a workaround if you wanted to run one of the upstream kernel builds the Ubuntu kernel team has began producing, the more recent ones (eg 2.6.29 or 2.6.30-rc1) should contain the patch in question. https://wiki.ubuntu.com/KernelMainlineBuilds . Thanks.

confirmed. workaround works in latest Jaunty build.

Which kernel update will see the fix committed? My E2500 is still not working with the latest kernel as of 18 April 2009 on Jaunty.

Leann's post makes it clear that there will not be a fix until after release of Jaunty. The Kernel is in code freeze pending release. However, the work around posted works fine for me. It's not hard. simply go here:

http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.29.1/

Download the Kernel image for your architecture and install it with the package installer that will open it automatically. Then Restart.

For me, the New Kernel fixed the camera, but it made some other things a little funky. So I edited grub so that the 2.6.29.1 kernel was the second boot option. When I want to use the Camera, I reboot and select that kernel. That should hold you over until the fix is in.

can you please test the kernel in http://people.ubuntu.com/~manjo/lp326674-jaunty/ and report back here ?

Sorry, I don't have an AMD 64. If you have a 86 based kernel I can test
that.

Hi Manoj

Sorry, I had trouble compiling my own kernel - it is not easy with linux-source...

Anyway, the kernel from http://people.ubuntu.com/~manjo/lp326674-jaunty/ works in so far as the camera is detected, and I can get a picture with cheese. The quality in 640x480 is horrible (way to dark), but 320x240 is alright, very responsive, if a bit noisy.

I do get a lot of error message on the console like

libv4lconvert: Error decompressing JPEG: unknown huffman code: 0000ffff

(and similar numbers), so the support does not seem perfect yet. But it is much better than nothing.

ekiga crashes, whether I use the webcam or not, so I cannot test that.

submitted sru for jaunty.

The kernel from Manoj works for me. I can use the webcam in Skype.

the mainline kernel v2.6.29.1 works for me althought it messes up my wifi and video card

SRU JUSTIFICATION:

IMPACT: Logitech Quickcam E2500 not supported
FIX: patch added to recoginize USB webcam 046d:089d
TEST: The originator of the bug tested the kernel
http://people.ubuntu.com/~manjo/lp326674-jaunty/ and reported that the
camera is detected but the image quality is poor in 640x480 but good for
320x240.

Accepted linux into jaunty-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

confirmed that the new kernel package fixes this for me in Jaunty - no issues with hardware detection or video in Cheese after upgrading from the proposed repository.

$ dpkg -s linux-image-2.6.28-11-generic
Package: linux-image-2.6.28-11-generic
[snip]
Version: 2.6.28-11.42

i can also confirm that with the jaunty proposed update webcam works w/cheese. In order for the webcam to work with skype, i am using the fix from this forum:

http://ubuntuforums.org/showthread.php?t=993262

I just enabled Jaunty Proposed, and straight away the Quickcam E2500 works, albeit with a small green margin in the bottom of the frame.

Works with Skype straight out of the box, and the sound quality with Skype is far superior to the ratty old budget, budget, budget webcam I bought for NZ9ドル.01 in an online auction when the Logitech wouldn't work on Intrepid: the sound quality makes up for the green line.

Nice work, those responsible!

Regards,
Bruce.

Problem still exists on the updated (with proposes) installation of Jaunty.

Messy video under skype (green chaotic pixels, mixed with red and black ones ;).

Works with mplayer, but stopped after few seconds.

root@mujo:/home/bluszcz# uname -a
Linux mujo 2.6.28-13-generic #44-Ubuntu SMP Tue Jun 2 07:57:31 UTC 2009 i686 GNU/Linux
root@mujo:/home/bluszcz#

I can confirm the behaviour described by Rafal Zawadzki. Some more information from my side:

System: Dell Inspiron 1525 (one of their Ubuntu Linux Notebooks)

Installation: Kubuntu Jaunty with all current updates (no backports or proposed)

Skype
====
Camera is now recognized but shows merly green/black noise (see attachment; this happens after clicking on the 'test' button ). However the picture is not constant (framerate would be quite normal I think, around 30fps?). Often Skype just crashes after clcking on 'test'.

Kopete
=====
Camera is now recognized but shows only a black square (see attachment). Reading the kopete logs it looks like the camera is reporting that it can hardly produce any valid output-image formats, or does a kopete log always look like this?

/dev/video0
============
"cat /dev/video0" reveals that the camera is acutally producing output

Cheese
======
Camera actually WORKS here. Quality is unusuable with 640x480 but works OK with 320x240 (although worse than under Windows). However I cannot make any photos with cheese (it basically does not produce any file) nor any movies (when I click on record the video area shows only a black area and when I click on stop, cheese crashes)

I also added the cheese logs (generated by starting cheese from the command line) which reveals some errors, that might be relevant.

Furthermore I just installed linux-image-2.6.30-020630-generic_2.6.30-020630_i386.deb and the accompanying header files (taken from Ubuntu Mainline Kernel packages). Here, the problem is still the same as described above.

It seems more like v4l problem, can you try with export LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so ?

Hi,

I have the same problem as sewert (same screenshot, same logs etc).

I can see that a fix has been released but I never seen it.

Thanks in advance for your answer

I have exactly the same problem as sewert and Solvik. Same screenshot and same logs.

Configuration:
Notebook: HP EliteBook 2530p
Ubuntu: 9.04 (latest updates until 30/01/2010)

Thank you in advance.

Kernel: Linux horat 2.6.28-17-generic #58-Ubuntu SMP Tue Dec 1 18:57:07 UTC 2009 i686 GNU/Linux

I found a temporal solution for it. If I execute
LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so skype
it works as suggested by Manoj lyer.

I created a bash script to execute it and that is what I call from the Ubuntu Menu.

I can get the camera to work in cheese, however, after a few seconds, the captured image turns very dark. I tried some module parameters like autoexposure=0 , but that didn't seem to help.

I'm running a straight karmic, but custom kernel/drivers are compiling as I typie. I'm going to try to the linuxtv.org git repositories.

My goal is to use the cam as zonefinder source. Anyone else have any newer experiences with this beast ?

I have problem like Michael. Camera with latest gspca driver works fine until it randomly goes dark. is there any workaround? Thanks...
