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.

Re: Webcam module & CDROM Permission

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 wink

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. big_smile

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.
