Description Slawek Ligus 2006-06-08 10:02:58 UTC

Customer cannot write data on CDs with k3b. Program
sees CD writer /dev/sr1 as a read-only device. 

Manual edition by "add device" gives error msg:
"Could not find an additional device at /dev/sr1"
 
It is possible to burn a cd with cdrecord and xcdroast

sginfo -l output:
/dev/sr1 /dev/sr0 /dev/sda
/dev/sg0 [=/dev/sda  scsi0 ch=0 id=0 lun=0]
/dev/sg1 [=/dev/sr0  scsi0 ch=0 id=1 lun=0]
/dev/sg2 [=/dev/sr1  scsi1 ch=0 id=1 lun=0]

I don't know how k3b handles SCSI devices, but /dev/srX are by definition read-only devices. It might be that /dev/sgX must be used instead. Like /dev/sg1 instead of /dev/sr1

>I don't know how k3b handles SCSI devices, but /dev/srX are by definition
>read-only devices. It might be that /dev/sgX must be used instead. Like
>/dev/sg1 instead of /dev/sr1

This is a bit confusing with /dev/sr* and /dev/sg*.
I open the k3b setup and see under the devices:
YAMAHA CRW2100S     /dev/sr1
YAMAHA CRW2100S     /dev/sg2
So, k3b seems to recognize the CD-RW under both devices: /dev/sr1 AND /dev/sg2
But in the configure menu "devices" it is only /dev/sr1

When I try under 'configure' 'add device ...' to add /dev/sg2 I get "Could not find an additional device at /dev/sg2".

Is there a way to add/change devices under k3b?

Comment 6 Hartmut Meyer 2006-06-08 12:45:50 UTC

I cannot test this with SCSI devices (I don't have any). But in the k3b configure ("k3b einrichten ...") dialoge you can "add device" ("Gerät hinzufügen ...").

Try with /dev/sg1

Again: it might be that k3b claims to use the /dev/srX devices in order to make it easier to understand for the average user (many don't know about /dev/sgX) even when it really is using the corresponding /dev/sgX device file instead.

Does your YAMAHA CRW2100S work with k3b in SUSE Linux 10.1?

Comment 7 Ulrich Hiller 2006-06-08 13:00:54 UTC

I can do it for you if you tell me what to do ....

I get the message: "Could not find an additional device at /dev/sg1"

>Again: it might be that k3b claims to use the /dev/srX devices in order to make

The question is how I can switch it without getting the message "Could not find an additional device at ....."

> Does your YAMAHA CRW2100S work with k3b in SUSE Linux 10.1?

Only as a readonly device (in opposite to SuSE 10.0 where I could burn).
But I am, under 10.1, able to burn with cdrecord and xcdroast.

Comment 8 Hartmut Meyer 2006-06-08 13:17:18 UTC

Ulrich, what is the output of

  sginfo -l

?

Comment 9 Hartmut Meyer 2006-06-08 13:53:41 UTC

I just heard from Slawek, that you are the customer he was talking about.

Ok, so please try with

  /dev/sg2

("sginfo -l" said that /dev/sr1 -> /dev/sg2)

Comment 10 Ulrich Hiller 2006-06-08 14:00:50 UTC

'sginfo -l' gives

/dev/sr1 /dev/sr0 /dev/sda
/dev/sg0 [=/dev/sda  scsi0 ch=0 id=0 lun=0]
/dev/sg1 [=/dev/sr0  scsi0 ch=0 id=1 lun=0]
/dev/sg2 [=/dev/sr1  scsi1 ch=0 id=1 lun=0]


>Ok, so please try with
>
>  /dev/sg2

You mean adding the the device /dev/sg2 in k3b?

That gives 
"Could not find an additional device at /dev/sg2"

Or did I misunderstand you?

Comment 11 Hartmut Meyer 2006-06-08 14:08:32 UTC

Yes, that is what I meant.

And since it's not working, we can only wait for the developers (or another person with a SCSI CD/DVD writer) to give some input.

My idea about /dev/sgX instead of /dev/srX might have been wronge anyway ...

For completenes, could you please also provide us with the output of

  hwinfo --cdrom

?

Comment 12 Stephan Kulow 2006-06-08 14:12:54 UTC

I only have a SATA burner and it works just fine there ;(

Comment 14 Forgotten User RlXLgpWK5h 2006-06-17 17:17:09 UTC

I can second this bug. I have the same CD-R Writer and the same Problem!

Comment 15 Forgotten User RlXLgpWK5h 2006-06-17 21:40:46 UTC

sorry .. i have
Vendor_info    : 'YAMAHA  '
Identifikation : 'CRW4260         '
Revision       : '1.0j'
Device seems to be: Generic mmc CD-RW.

worked find under 10.0 ... only recognized as a reader with k3b (on /dev/sr0)
when trying to add /dev/sg0 manually, this does not work... X-CD-Roast also detects the writer not automatically but when adding as /dev/sg0 manually it works

hopefully someone will fix this bug soon, otherwise i must either downgrade to 10.0 or buy new hardware :(

Comment 16 Forgotten User RlXLgpWK5h 2006-09-13 12:04:54 UTC

okay.. this was not suses fault... i talked to developer of k3b and it is fixed in newer versions...

i am using k3b 0.12.17 now, and burning with my yamah scsi writer works fine :-)

Comment 17 Sebastian Trueg 2007-02-16 10:03:02 UTC

Will there be an updated k3b in suse 10.1? Can this bug be closed or do we need a patch?

Comment 18 Stephan Binner 2007-04-05 11:53:36 UTC

I don't think that we will make an online update for k3b on 10.1 anymore (except a security problem for it occurs). Feel free to attach a patch/mention the revision which fixed it for his case though.

PS: the latest k3b version 1.0 is available in the KDE build service project at http://software.opensuse.org/download/KDE:/Backports/SUSE_Linux_10.1/
