USB CDROM/DVD Device Problems on Ubuntu 10.10

[SebMack]

Ubuntu 10.10 seems to have troubles with cdroms...I used Ubuntu 8.04 lts and 10.04 lts with no cdrom issues.
10.10 does not show my CDROM/DVD USB device in 'Places' and I cannot get it's UUID number via ROOT terminal , yet I did Remastersys backup of entire system, opened the Remastersys folder, right clicked the custom.iso file and burnt it using Brasero, which proves it is working on 10.10 but just not showing an icon. Inserting media of any kind does not open the Nautilus folder, yet other USB devices show immediately (USB sticks and USB harddrive appear instantly).

The CDROM/DVD USb device works in Windows on a different machine and I also attached a USB harddrive with Windows XP to my netbook which 10.10 is installed on, and the USB CDROM/DVD device shows up fine.
I tried mounting the device in Ubuntu 10.10, but I'm not that great at understanding commands, and the hundreds of different commands other people tried across the web don't work.

When I type 'dmesg' the USB CDROM shows up as this (is there an I/O error preventing the USB cdrom drive from displaying???):-

[ 8284.535666] scsi 9:0:0:0: CD-ROM HL-DT-ST DVDRAM GSA-4084N KQ09 PQ: 0 ANSI: 0

[ 9001.957325] JBD2: I/O error detected when updating journal superblock for sdc1-8.


Also typing this below showed my device:-
'ls /dev/disk/by-id -lah'

I also typed 'lsusb' and my device showed up on line 6 as 'Genesys Logic, Inc . USB 2.0 IDE Adapter'

but typing this only displayed my internal HDD UUID number on line 4:-
'ls /dev/disk/by-uuid -lah'

My USB CDROM/DVD device installed Ubuntu 10.10 just perfect, but then it disappeared some time without me noticing. Reinstallation does not help, the device still won't appear...It doesn't show up in fstab or mtab.
This has only been an issue since I installed 10.10 netbook edition. I am currently using GNOME because it uses less CPU power and is more configurable.

What Ubuntu 10.10 needs is a CDROM detection and installation software program...in a .deb file, so it can be downloaded, installed and opened like a normal program, and would be able to detect a CDROM or DVD attached, and create it within fstab and other files requiring the info...
If Windows has been able to detect CDROM's since the 1990's I can't see why Ubuntu suddenly has problems..
People shouldn't have to be subjected to a crash course in programming to add basic standard devices.

thanks for reading my whinge.

From my lsusb:

Bus 001 Device 006: ID 05e3:0701 Genesys Logic, Inc. USB 2.0 IDE Adapter

From my dmesg:

When I plug in and switch on the USB DVD drive, a second 'CD/DVD Drive' icon appears in Places > Computer (this is a Desktop system with an internal DVD drive running the standard desktop Ubuntu 10.10). But when I put a readable DVD in, the drive whirrs for a bit and then the second icon disappears. It would appear that you have uncovered a bug which I have probably reproduced, except that my dmesg shows no error after disconnecting the device.

So....

... instead of "whingeing" and making assumptions about what Ubuntu might or might not "need", why not pop over to...

https://bugs.launchpad.net/ubuntu/

... and file a bug report?

After you.

Edit: The fact that I couldn't find a relevant bug on Launchpad means that this could be an obscure bug affecting only some types of USB hardware. This is quite possible. When you consider the variables of the kernel driver, the ACPI implementation in the BIOS and the USB device's firmware, the possible permutations are endless. I'll give you an example. I have a USB SATA docking station. Works just fine with every machine and OS I have except with my Sony Vaio running an earlier version of Ubuntu (can't remember which offhand). It worked fine with the same Ubuntu version on other machines, just not with the Sony. But it worked fine with Vista on the Sony. Why? Haven't a clue and life is too short for me to worry about it.

Out of interest, what is your USB CD/DVD enclosure? I assume it was a bare enclosure when you bought it because it has the same ID '05e3:0701' as mine which is a 'Hiyatek'. But googling '05e3:0701' brought up a variety of makes all with the same ID. For example.

I think I may be right. I've managed to get hold of one of those USB powered external DVD drives that use a slimline drive to try out. It is recognised and automounted in Ubuntu 10.10 just fine. Presumably then this problem must be a bug affecting...

Bus 001 Device 006: ID 05e3:0701 Genesys Logic, Inc. USB 2.0 IDE Adapter

... because I've tried this device with another machine running 10.10 and I get the same issue.

Is this is bug? Almost certainly. Is it irritating/frustrating? Undoubtedly. Will it get fixed? Not unless someone files a bug report. Will it get fixed then? Depends on how many people do a 'me too' on the bug report. Seeing as how this seems to be hardware-specific to a fairly uncommon piece of hardware I would guess this affects only a small minority of Ubuntu users.

I'm posting this workaround for anyone with a similar problem who's found this thread from a search. I doubt the OP is interested since they have not logged in since posting their one and only post.

Have a look in /dev. If you have a machine without an internal optical drive, your usb CD/DVD drive will probably appear as sr0. If you have an internal CD/DVD drive, your usb one will probably be sr1. If it doesn't automount when you insert a CD or DVD, simply open a terminal and:

udisks --mount /dev/sr0

... or ...

udisks --mount /dev/sr1

... depending on whether you have an internal optical drive or not. Your disc will be mounted and a clickable icon will appear on the desktop with a 'disk' label.

It is not elegant but at least someone in the OP's situation will be able to read CDs and DVDs.

I have the exact same problem but it is limited to Audio CDs (haven't checked Media DVDs). Software DVDs work fine.

I tried the workaround on an audio CD, but this didn't work:
ml@computer:~$ udisks --mount /dev/sr1
Mount failed: Error mounting: mount: block device /dev/sr1 is write-protected, mounting read-only
mount: you must specify the filesystem type[/code]So then I tried this, but didn't work as well:

 
ml@computer:~$ udisks  --mount /dev/sr1  --mount-fstype cdda
Mount failed: Not a mountable file system

I am not sure about the cdda option tho...

What am I missing ?

Many thanks!

OK - after browsing along some more - I got to understand that Audio CD's are not to be "mounted", but rather accessed directly through the software.

Anyhow - the problem remains that Ubuntu - or is it a problem with Gnome ? - cannot see the Audio CD's from the USB/IDE adaptor using the 05e3:0701 Genesys Logic, Inc. chip set.

This work for me. Thanks coffeecat.
I have Ubuntu 10.10. When I connect my usb cdrom ubuntu detects and install correctly.
This is what dmesg show my:

[ 2038.373076] usb 1-2: new high speed USB device using ehci_hcd and address 19
[ 2038.512312] usb-storage 1-2:1.0: Quirks match for vid 05e3 pid 0701: 520
[ 2038.512400] scsi8 : usb-storage 1-2:1.0

[ 2039.550873] sr 8:0:0:0: Attached scsi generic sg3 type 5

But when insert a disk the icon un My Computer disapers.
Of course is not elegant. I go back to 10.04 because this problem, the hibernate and suspend problem and because my webcam doesnt work here and in 10.04 yes.

[davidstoll]

I also have this problem and the solution/workaround worked for me. However, how do I make it mount automatically when I plug in the external drive?

[manco]

udisks --mount /dev/sr0

udisks --mount /dev/sr1

^ Worked like a charm! Thanks a million!
