k3b has problems using a USB writer

[Vide]

I'm using a Breezy fresh install, installed from the same USB drive having
problems.
I have two CD-ROM drives in my PC, an IDE one (only reader) and a USB one,
that's a recorder.

This obviously cause problem while trying to burn a CD with Nautilus, K3b and
whatever frontend I try.

Ok, more infos: the sg0 device is my hard disk, so the group is correct, while
sg1 is the burner, and even here the group is correct.
So it seems like http://bugzilla.ubuntu.com/show_bug.cgi?id=8036
 BUT the solution doesn't work, and in fact the problem is appearing on a breezy
box. I do have checked the /etc/cdrecord/cdrecord default parameter and it set
to /dev/cdrw, which points correctly to scd0

lrwxrwxrwx 1 root root 4 2005-11-08 13:24 /dev/cdrw -> scd0

brw-rw---- 1 root cdrom 11, 0 2005-11-08 13:24 /dev/scd0

the problem is that K3b on Ubuntu/Kubuntu doesn't seem able to really specify to
cdrecord the device to use, even if I have selected it in the K3B device list.
So maybe this is a k3b bug?

[Scott James Remnant (Canonical) (canonical-scott)]

udev appears to be doing exactly the right thing (except for that symlink, which
is dropped now anyway)

[aexl (aexl)]

i had exactly the same problem. eveything worked fine after i added the following setting in k3b:
options > Programs > userdefined-parameters > cdrecord
dev=/dev/sg1:1,0,0

background:
the key was the line:
>Error trying to open /dev/sg0 exclusively (Permission denied)
(where sg0 is NOT the CDRW but my hard drive which has permissions 660 root.root)
k3b calls cdrecord with parameter dev=1,0,0
i assume(!) that cdrecord does a scanbus to guess the device. which as non-root gives me said error.

if k3b specified the device node as i did the issue would be solved.
so imho this really is a K3b issue.

[Kenny Duffus (kduffus)]

do you still have this problem? k3b should be giving you a pull down menu with devices

[Mikael Nilsson (mini)]

This is certainly still a problem.

Upstream: http://bugs.kde.org/show_bug.cgi?id=122568

[Mikael Nilsson (mini)]

Oh, please note that this affects my built-in writer on /sys/class/scsi_device/1\:0\:0\:0/

I think the main problem is when using SATA hard drives.

I'm sorry that I can't help you anymore tracking this problem but I do not have anymore access to the hardware on which I was experiencing problems. I hope other people that could reproduce this bug can help :)

[Mario Đanić (mario-danic)]

This bug has been fixed upstream.

[Dirk Freitag (unr3a1-r00t)]

I am having this issue even with the latest k3b version. I tried all the things listed here, but cannot get it to work.
