Webcam module & CDROM Permission

Yesterday i tried to make webcam working. I follow this wiki http://wiki2.archlinux.org/index.php/qc-usb to make it work. It says that ther should be a module called "quickcam". But I can't find it.

Can you help me with that?

Another thing that is wrong, that i don't have permission to use my cd- and dvd-drive. I have added myself to the optical group:

optical:!:93:mikkel

And i have also tried to modify the /etc/devfsd.conf, but i hasn't helped. I have modify it 3 times:

# Permissoins for optical devices
REGISTER        ^cdroms/.*      PERMISSIONS     root.optical 0660
 [b]and[/]
# Permissoins for optical devices
REGISTER        ^cdroms/.*      PERMISSIONS     root.optical 660
 [b]and[/b]
# Permissoins for optical devices
REGISTER        ^cdroms/*      PERMISSIONS     root.optical 660

But nothing has worked. What should I do?[/code]

Re: Webcam module & CDROM Permission

Did you install quickam driver package ? (pacman -S qc-usb26). You can list files in the package using pacman -Ql qc-usb26.

Are you using devfs or udev ? If you're using udev take a look at /etc/udev/rules.d.

I am not quite sure about that, but I think I use devfs.

Re: Webcam module & CDROM Permission

I got this when I ran pacman -Ql qc-usb26

[root@matrix mikkel]# pacman -Ql qc-usb26
qc-usb26 /lib/
qc-usb26 /lib/modules/
qc-usb26 /lib/modules/2.6.9-ARCH/
qc-usb26 /lib/modules/2.6.9-ARCH/kernel/
qc-usb26 /lib/modules/2.6.9-ARCH/kernel/drivers/
qc-usb26 /lib/modules/2.6.9-ARCH/kernel/drivers/usb/
qc-usb26 /lib/modules/2.6.9-ARCH/kernel/drivers/usb/misc/
qc-usb26 /lib/modules/2.6.9-ARCH/kernel/drivers/usb/misc/quickcam.ko
qc-usb26 /usr/
qc-usb26 /usr/bin/
qc-usb26 /usr/bin/qcset

The thing is, that I don't use kernel 2.6.9-ARCH, but kernel 2.6.11-7-ARCH. Is that a problem?

Re: Webcam module & CDROM Permission

It probably need to be rebuild for the new kernel.  Submit a bug report.  There is also a patch: http://forums.archlinuxfr.org/viewtopic.php?t=187

I can provide a translation if you have problem with French

Re: Webcam module & CDROM Permission

Just wanted to say, that my cdrom permission problem i solved. I just guess that iis was because my /etc/fstab lokk like this before:

/dev/cdroms/cdrom0     /mnt/cd   auto      ro,user,noauto,unhide   0      0
/dev/cdroms/cdrom1     /mnt/dvd  auto      ro,user,noauto,unhide   0      0
/dev/floppy/0          /mnt/fl   auto      user,noauto             0      0
/dev/sda               /mnt/usb  auto      user,noauto             0      0

Changed 'users' to be 'user' instead.

Thanks for helping anyway.

OK. It seems that the patch isn't needed as it was incorporated in the cvs. Here's the PKGBUILD for the cvs version of qc-usb26.I don't know how stable it is though...
You should still submit a bug report if you haven't done it yet so that the official package get fixed.

pkgname=qc-usb26
pkgver=20050417
pkgrel=1
pkgdesc="Logitech quickcam webcam drivers"
url="http://qce-ga.sourceforge.net"
license=""
depends=()
makedepends=(cvs)
install=
cvsroot=":pserver:anonymous@cvs.sourceforge.net:/cvsroot/qce-ga"
cvsmod="qc-usb"
kernelver=$(uname -r)
build() {

  cd $startdir/src/
  msg "Press enter."
  cvs -Q -d $cvsroot login

  msg "Fetching sources from CVS..."
  cvs -Q -z3 -d $cvsroot co $cvsmod
  cd $cvsmod
  sed -i 's|-pipe|-pipe -fno-unit-at-a-time|g' Makefile
  make all

  mkdir -p $startdir/pkg/lib/modules/$kernelver/kernel/drivers/usb/misc
  cd $startdir/src/qc-usb
  cp quickcam.ko $startdir/pkg/lib/modules/$kernelver/kernel/drivers/usb/misc/

  mkdir -p $startdir/pkg/usr/bin
  cp qcset $startdir/pkg/usr/bin/
}

Re: Webcam module & CDROM Permission

Before I try the CVS. I just wanted to now, if I just could delete qc-usb26. I forgot to tell that I used kernel 2.6.10-something for a few days ago (I installed Arch in Friday).

Re: Webcam module & CDROM Permission

Yes, remove the package with pacman -R qc-usb26. And you need to recompile it for the current kernel version you are using now. qc-usb26 is in staging repo and it's probably in the process of transformation to AUR system (like many packages) so things like this can happen now - be patient.

Be a good archer and recompile the package yourself using ABS :-)

BTW If you are using devfs I'd recommend you to switch to udev:

Re: Webcam module & CDROM Permission

I downloaded qc-usb driver from http://qce-ga.sourceforge.net/ but it says my webcam isn't compatable:

I can find the following probably compatible devices:
[!] Didn't find compatible cameras.
If you got message: "Permission denied", it means that
you simply have too old lsusb, and you can ignore this problem.
In this case you have to be root to use lsusb, but I won't do that.
WARNING: If you press Enter, I'll try to continue anyway,
but this probably will fail. You SHOULD press Ctrl+C now.
Press Ctrl+C to quit, Enter to continue ---> 

Do anyone now another driver I can use? I have a Logitech Quickcam Communicate Plus.

Re: Webcam module & CDROM Permission

As it says on the qce-ga web page:

An experimental driver for QuickCam Messenger was recently written by Mathias Küster and improved by Christian Magnusson, including support for QuickCam Communicate. A mirror is also available, if the original site doesn't work.
