No, I don't think so, bug 259141 is about problems with hal/CK integration, this is about a kernel driver bug. Confirming that this is also a problem with F-8. I can't even get a picture with camstreams or ekiga as root on F-8 with kernel-2.6.23.15-137.fc8 I see this repeated in /var/log/messages when I try to acquire an image.

F7 wworks ok, but problem exists in F8. There's also problem with picture. When testing with mplayer the picture remains blank green. Here's my /var/log/messages after plugging it in: usb 5-1: new full speed USB device using uhci_hcd and address 5 usb 5-1: configuration #1 chosen from 1 choice ALSA sound/usb/usbaudio.c:2753: 5:2:1: add audio endpoint 0x83 ALSA sound/usb/usbmixer.c:989: [2] FU [Mic Capture Switch] ch = 1, val = 0/1/1 ALSA sound/usb/usbmixer.c:406: cannot set ctl value: req = 0x4, wValue = 0x200, wIndex = 0x201, type = 4, data = 0x80/0x0 ALSA sound/usb/usbmixer.c:989: [2] FU [Mic Capture Volume] ch = 1, val = -14080/0/256 ALSA sound/usb/usbmixer.c:989: [2] FU [Auto Gain Control] ch = 1, val = 0/1/1 drivers/media/video/usbvideo/quickcam_messenger.c: Logitech Quickcam Messenger USB v0.01 videodev: "QCM USB Camera" has no release callback.

If I manually "chmod 666 /dev/video0", the camera works perfectly in Ekiga for a regular user. Does anyone know a more automatic workaround? device node permissions problems will be a userspace issue. Probably udev. The -28 which Alex hits is the lack of the bandwidth. It's a murky area, we used to have bugs when things like 2.0 hubs claimed too much. But I think F8 is pretty good there, it's most likely really not enough bandwidth. The annoying thing is, the devices report how much they need, but often they use less. You'd think the cam would fit on an empty bus, but actually it won't share with a mouse sometimes. Solution: plug into a root hub. Permissions for Gustavo and Mattias is something for Harald to look at. It has to do with udev, not kernel. I confirm that e.g. "chmod 666 /dev/video1" makes the webcam work with ekiga. Changing version to '9' as part of upcoming Fedora 9 GA. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping Reconfirming that this still doesn't work for me with Fedora 9 kernel-2.6.25.4-30.fc9.i686. I still have the same problem as I described in comment #3. Nothing, including camstreams shows a picture, here's the /var/log/messages: Jun 9 22:37:34 binoche kernel: usb 1-2: new full speed USB device using uhci_hcd and address 5 Jun 9 22:37:34 binoche kernel: usb 1-2: configuration #1 chosen from 1 choice Jun 9 22:37:34 binoche kernel: videodev: "QCM USB Camera" has no release callback.

What exactly is a root hub? This isn't hanging off another hub that this then plugged into the computer. I have it plugged directly into one of the two USB ports on the back of the machine. Should I try the other USB port? (In reply to comment #11) > I have it plugged directly into one of the two USB ports on the back of the > machine. Should I try the other USB port? The second USB port does have a PS-2 mouse and PS-2 keyboard plugged into a USB splitter which then plugs into the computer. Could that be the problem?

That device could be claiming enough bandwidth to prevent the camera from working. Are those two the only ports available? This message is a reminder that Fedora 9 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 9. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '9'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 9's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 9 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping Fedora 9 changed to end-of-life (EOL) status on 2009-07-10. Fedora 9 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed. |
The quickcam_messenger driver does something wrong. When I plug this webcam in, I get a /dev/video and /dev/video0, and the camera works for root, but [mclasen@localhost devel]$ tree /sys/class/video4linux /sys/class/video4linux `-- video0 |-- dev |-- name |-- subsystem -> ../../../class/video4linux `-- uevent is missing device and driver links, so hal doesn't know how to handle it...
