gravity dev #

and it appears
but | Code: | gravity dev # mount -t auto /dev/sg0 /mnt/cdrom
mount: /dev/sg0 is not a block device
gravity dev # cat /etc/fstab

| Try with /dev/sr0 (or maybe /dev/scd0) instead of /dev/sg0. /dev/sg0 is a low-level interface and not the block device. |

Could those errors be caused by the "Probe all LUNs" option in the kernel's SCSI config section? If so, they'd be meaningless & harmless.

| What happens if you create the node yourself (with "mknod /dev/scd0 b 11 0") ? Also /dev/scd0 is sometimes called /dev/scda instead. |

created the node
then | Code: | gravity / # ls -la /dev/sc*
brw-r--r-- 1 root root 11, 0 Sep 4 21:44 /dev/scd0
gravity / # mount -t iso9660 /dev/scd0 /mnt/cdrom
mount: /dev/scd0 is not a valid block device
gravity / # |

ive come across this - dont know if its relevant .Currently the CDRom is the only USB storage device I have attached
| Code: |
gravity dev # cat /etc/mtab
/dev/hda3 / ext2 rw,noatime 0 0
proc /proc proc rw 0 0
sysfs /sys sysfs rw 0 0
udev /dev tmpfs rw,nosuid 0 0
devpts /dev/pts devpts rw 0 0
/dev/hda1 /boot ext2 rw,noatime 0 0
none /dev/shm tmpfs rw,noexec,nosuid,nodev 0 0
usbfs /proc/bus/usb usbfs rw,devmode=0664,devgid=85 0 0
gravity dev # |
googling ,ive come upon lsscsi
without it plugged in
| Code: |
gravity dev # lsscsi
gravity dev # lsusb
Bus 004 Device 001: ID 0000:0000
Bus 003 Device 002: ID 062a:0001 Creative Labs Notebook Optical Mouse
Bus 003 Device 001: ID 0000:0000
Bus 002 Device 001: ID 0000:0000
Bus 001 Device 001: ID 0000:0000
|
with it plugged in
| Code: |
gravity dev # lsscsi
[1:0:0:0] cd/dvd ASUS SCB-2408 1.2B -
gravity dev # lsscsi -lvH
[1] usb-storage
cmd_per_lun=1 host_busy=0 sg_tablesize=255 unchecked_isa_dma=0

Bus 001 Device 004: ID 2821:5001
Bus 001 Device 001: ID 0000:0000

still not working .Having googled a lot Ive added in
SCSI CDROM support in the kernel
| Code: | │ │ --- SCSI device support
│ │ [*] legacy /proc/scsi/ support
│ │ --- SCSI support type (disk, tape, CD-ROM)
│ │ <*> SCSI disk support
│ │ < > SCSI tape support
│ │ < > SCSI OnStream SC-x0 tape support
│ │ <*> SCSI CDROM support
│ │ [*] Enable vendor-specific extensions (for SCSI CDROM)
│ │ <*> SCSI generic support
│ │ --- Some SCSI devices (e.g. CD jukebox) support multiple LUNs
│ │ [ ] Probe all LUNs on each SCSI device
│ │ [ ] Verbose SCSI error reporting (kernel size +=12K)
│ │ [ ] SCSI logging facility
│ │ SCSI Transport Attributes --->
|
ive now got
| Code: | gravity linux # grep ^[A-Za-z0-9] .config |grep USB

gravity linux # |
but | Code: |
gravity usb # mount -t iso9660 /dev/sg0 /mnt/cdrom
mount: /dev/sg0 is not a block device
gravity usb # |
but sr0 has appeared
| Code: |
gravity dev # mount -t iso9660 /dev/sr0 /mnt/cdrom
mount: block device /dev/sr0 is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/sr0,
or too many mounted file systems
gravity dev # mount -t auto /dev/sr0 /mnt/cdrom
mount: block device /dev/sr0 is write-protected, mounting read-only
mount: /dev/sr0: can't read superblock
gravity dev # |
a bit nearer but not there yet

still struggling to get this working
Ive emerged kaffeine.
When I plug in my drive a dekstop icon for CDRecorder appears and it tries to mount media:/sr1
and then I get
| Quote: | mount block device /dev/sr1 is write-protected, mounting read-only
mount :/dev/sr1:cant read superblock |
with an audio CD in the drive
and a with a dvd and mplayer
| Quote: | | Couldnt open DVD device :/dev/dvd |
[code]gravity dev # ls -la |grep dvd

updating udev has solved the DVD/CDROM problem. DVDs are now recognised and play and CDROMS are recognised from kaffeine.
The only problem is that sound doesnt work anymore
follow a thread with this in if i cant easilyfind an answer | Quote: | gravity .ssh # /etc/init.d/alsasound restart
* Loading ALSA modules ...
* Restoring Mixer Levels ...
/usr/sbin/alsactl: set_control:894: warning: name mismatch (Master Playback Switch/Master Playback Volume) for control
/usr/sbin/alsactl: set_control:896: warning: index mismatch (0/0) for control #1
/usr/sbin/alsactl: set_control:898: failed to obtain info for control #1 (Operation not permitted)
