smae things with newer 1.0.3...
Same problems here, too. This is pretty nasty. As with Carlo, mounting does work normally, even gnomebaker does recognize my external dvd writer. But as soon as I start k3b the device gets offline (while trying to get drive capabilities). Burning with growisofs from commandline does work. I have prepared some output from k3b which shows where the error occurs. After the last line k3b says it does not find a cd/dvd writer and the device is unusable until I unplug/unpower it. --- snip /dev/scd0 resolved to /dev/scd0 /dev/scd0 is block device (0) /dev/scd0 seems to be cdrom bus: 9, id: 0, lun: 0 (K3bDevice::Device) /dev/scd0: init( (K3bDevice::Device) /dev/scd0 feature: CD Mastering (K3bDevice::Device) /dev/scd0 feature: CD Track At Once (K3bDevice::Device) /dev/scd0 feature: DVD Read (MMC5) (K3bDevice::Device) /dev/scd0 feature: DVD+R (K3bDevice::Device) /dev/scd0 feature: DVD+RW (K3bDevice::Device) /dev/scd0 feature: DVD+R Double Layer (K3bDevice::Device) /dev/scd0 feature: DVD-R/-RW Write (K3bDevice::Device) /dev/scd0 feature: Rigid Restricted Overwrite (K3bDevice::Device) /dev/scd0 feature: Layer Jump Recording (K3bDevice::Device) /dev/scd0: dataLen: 60 (K3bDevice::Device) /dev/scd0: checking for TAO (K3bDevice::Device) /dev/scd0: checking for SAO (K3bDevice::Device) /dev/scd0: checking for SAO_R96P (K3bDevice::Device) /dev/scd0: checking for SAO_R96R (K3bDevice::Device) /dev/scd0: checking for RAW_R16 (K3bDevice::Device) /dev/scd0: checking for RAW_R96P (K3bDevice::Device) /dev/scd0: checking for RAW_R96R (K3bDevice::ScsiCommand) failed: command: GET PERFORMANCE (ac) errorcode: 0 sense key: NO SENSE (2) asc: 0 ascq: 0 (K3bDevice::Device) /dev/scd0: GET PERFORMANCE length det failed.

Same issue for me. I just bought an external IBM (NEC) DVD+-RW writer. The writer hangs/is offlined at the time where k3b is "checking for RAW_R96R". After this, k3b stays hung, and further lsusb command as well. I need to unplug the device to unfreeze them. DISTRIBUTION: OpenSuse 10.3.

I tested my DVD writer on another computer (which has OpenSuse 10.2 and an earlier kernel version), which produces the same issue. Is there a way to disable the checking for RAW_R96R?
Ok I tried to remove that RAW_R96R detection, but now the last debug message I see is "checking for RAW_R96P". The problem must be in the code that is executed later. BTW: if a CD/DVD is in the tray it doesn't affect the issue. I will try to turn to older versions of k3b.
The k3b-1.0.3-32 version seem to hang on the speed detection (K3bDevice::Device::determineSupportedWriteSpeed). When I comment out the method, it runs a little further past the call to close() in K3bDevice::Device::init. But it still offlines my writer, seemingly trying to detect other things. This is where I gave up. I tried k3b version 1.0.1-6.1, and it also works for me. So there must be some difference in the device detection between 1.0.1 and 1.0.3. Or it could be some kind of side-effect produced by other changes.
I just installed k3b 1.0.4-2.1, and the problem doesn't appear any more. Thanks!
I've installed 1.0.4 but still same problem with cdrtools-2.01.01_alpha34 Upgrade to cdrtools-2.01.01_alpha36 solved (for me)
>I've installed 1.0.4 "but still same problem" with cdrtools-2.01.01_alpha34 >Upgrade to cdrtools-2.01.01_alpha36 solved (for me) EDIT: I'm not sure of this! Actually my [DVD/CD]-RW is off lined at the and of each burn. I think it may be for some incompatibility between my Magnex external USB/EIDE adapter and the LG GSA-4163B.
Did you check if it is a power supply issue? After it worked for me, I still had issues when burning at high speed. This also offlined my writer. I had to buy an external self-powered USB hub, and plug both of its cables (USB and power) into it, and now it doesn't offline any more. On my old Dell laptop burning didn't work at all (offlined writer), since the usb ports were too weak. The USB hub also solved it.
> Did you check if it is a power supply issue? No, I don't think so because I use a 350W ATX power switch to power all of my external peripherals (router[250mW], DVD-RW[10W], NAS[30W] and Laptop[75W]) ;)
I'm also seeing this, or something like it, with k3b 1.0.5 on opensuse 11.1 (kernel 2.6.27.7). The device (a lacie external dvd writer, identifies as "TSSTcorp CD/DVDW TS-L632L") works fine in windows, reads dvds fine in suse, works with growisofs (and nero linux, whatever that uses!). But as soon as I start k3b, I get: VFS: busy inodes on changed media or resized disk sr1 last message repeated 37 times usb 1-6: reset high speed USB device using ehc i_hcd and address 3 Which just cycles endlessly until I either close k3b or unplug the drive. I will attach the k3b output separately, as it's a little verbose. The (K3bDevice::Device) /dev/sr1: READ 10 failed! (K3bDevice::ScsiCommand) failed: command: READ (10) (28) errorcode: 70 sense key: NOT READY (2) asc: 4 ascq: 1 just repeats endlessly. I also found this unhelpful debian bug on the same issue with a different drive: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=500986 Things I've tried: different cables different power supply shutting down kded shutting down hal/dbus four different computers No luck. The problem may be a kernel bug or something, but only k3b seems to be affected. Has anyone been able to solve this?
Created attachment 30150 [details] k3b console output from startup to reset loop
I had a similar issue, but it occurred only when I put a DVD into the drive (CDs were fine). My problem was that speed detection would reset the drive. There are two speed detection techniques, so I disabled the one that makes it reset. Please have a look at https://bugs.kde.org/show_bug.cgi?id=171381
Thanks you Vincent, your idea in bug #171381 seems to avoid the problem, but I don't think it's actually getSupportedWriteSpeedsViaGP() that is the problem. Ultimately, all it does is a SCSI GET PERFORMANCE, which fails in the debug output I attached. I don't know if the failed GET PERFORMANCE is what causes the reset, but something else is causing the command to fail. dvd+rw-mediainfo also does a GET PERFORMANCE in quite the same way, and it works just fine. So something k3b does prior puts either the drive or something in the driver stack in a problematic state. So far, I have had little luck in tracking it down. Most of this stuff in k3b is similar to dvd+rw-mediainfo, though it happens in a different order. It is also harder to tell exactly what is executed in k3b just because there's more code and more code paths. I'm pretty sure it isn't GET CONFIGURATION, READ DISC INFORMATION or READ TRACK INFORMATION, but they happen in a few different places. I will keep looking, but anyone who understands k3b or SCSI better than I will have more luck. Vincent, if it is not too much trouble, could you try dvd+rw-mediainfo and see if it works with your drive?
Henryk, I have tried dvd+rw-mediainfo and it causes no problem to my external drive. My guess is that GET_PERFORMANCE followed by a certain sequence of commands causes the drive to reset. And maybe the mediainfo tool doesn't use the same sequence. It looks like k3b does more extended detections. In fact the GET_PERFORMANCE command doesn't seem to fail at all, since the method returns true. So maybe it just succeeded but causes some other side-effect for the following detections. You might try to comment out the following detections and see if it works. I didn't bother researching further at that time.
In my case, GET PERFORMANCE is what fails, perhaps it is different for others. For example: (K3bDevice::ScsiCommand) failed: command: GET PERFORMANCE (ac) errorcode: 70 sense key: NOT READY (2) asc: 4 ascq: 1 (K3bDevice::Device) /dev/sr1: GET PERFORMANCE length det failed. other things fail too, but this seems to be where the drive resets. GET PERFORMANCE is actually sent twice, once to determine the number of descriptors, and again once that has been determined. I never get to the latter in 1.0.5 because the former fails. Interestingly, in 1.0.1 the first part has: cmd[9] = 0; // first we read only the header in 1.0.5 this becomes: cmd[9] = 1; // first we read one descriptor I'm not sure what the difference is, but changing it back to the 1.0.1 way makes things work for me (without commenting out getSupportedWriteSpeedsViaGP in k3bdevice.cpp). Somewhat stranger, dvd+rw-mediainfo uses 1 in the tenth byte as k3b 1.0.5 does, but evidently without problem. So I go back to the idea that k3b does something to upset the drive which "1" then knocks over, but "0" doesn't. It is probably too much work for me to figure out what that is, so in the absence of a SCSI person telling me why the tenth byte must really be 1, I will patch my k3b to make it 0 as in 1.0.1 and wait for someone else to find the real difference. Anyone else having this problem should probably try first this patch (as it is a smaller change) and then Vincent's idea to see if either helps.

Hi, Same problem here. I've got a Vantec NexStar DX NST-530S2 external USB to SATA enclosure with a samsung SH-S223Q drive. When I launch k3b, the drive crashes and gets disabled with a : "(K3bDevice::ScsiCommand) failed: command: GET PERFORMANCE (ac)" error. On the other hand dvd+rw-mediainfo works fine, so I tried to compare the atapi commands sent to the drive. I tracked down the problem in the K3bDevice::Device::getPerformance() method. This method send a GET_PERFORMANCE command and only reads in the 8 bytes header response. I am not sure, but I believe from the ATAPI specs that the nominal performance descriptor is also sent back from the drive, making a 24 bytes response (that's what is implemented in dvd+rw-mediainfo). The attached patch fixes the problem. Thanks,
SVN commit 932014 by trueg: If we request one performance descriptor the buffer should provide the space to store it. Thanks to Christophe Bothamy for the patch. BUG: 147611 M +7 -7 k3bdevice_mmc.cpp WebSVN link: http://websvn.kde.org/?view=rev&revision=932014
