eeepc running eeebuntu not recognising usb DVD drive
Hi there.
I have a 701 loaded with eeebuntu (Hardy) and it does not recognise my usb DVD drive which is a Samsung Super-writemaster SE-S224. Boot from usb is enabled - any ideas? Thanjks |
Can you access the DVD drive when you are in Linux ?
is it only a boot time issue you are having with it ? |
no I cannot see it at all in Linux
|
In Linux open a terminal and type lsusb that should show your USB ports and anything connected to them..
for example.. Code:
Here is a listing before I attach a USB to Sata adapter with a DVD drive attached you can also view the message log to see the connection information of the device. Code:
it-etch:~ #tail /var/log/messages |
Thanks very much...
With drive plugged in I get: ian@ian-laptop:~$ lsusb Bus 004 Device 001: ID 0000:0000 Bus 003 Device 002: ID 0951:1606 Kingston Technology Bus 003 Device 001: ID 0000:0000 Bus 002 Device 004: ID 13fd:2040 Bus 002 Device 003: ID 03f0:0024 Hewlett-Packard Bus 002 Device 001: ID 0000:0000 Bus 001 Device 003: ID 1241:1177 Belkin F8E842-DL Mouse Bus 001 Device 001: ID 0000:0000 Without I get the same :-( There are three ports though and one has a mouse, the other an HP keyboard but what is the Kingston if it is not the usb DVD drive - nothing else plugged in? ian@ian-laptop:~$ tail /var/log/messages Nov 26 21:49:53 ian-laptop kernel: [ 870.360691] usb 2-1: configuration #1 chosen from 1 choice Nov 26 21:49:53 ian-laptop kernel: [ 870.375595] scsi5 : SCSI emulation for USB Mass Storage devices Nov 26 21:49:58 ian-laptop kernel: [ 871.905505] scsi 5:0:0:0: CD-ROM TSSTcorp CDDVDW SE-S224Q TS00 PQ: 0 ANSI: 0 Nov 26 21:49:58 ian-laptop kernel: [ 871.906817] scsi 5:0:0:0: Attached scsi generic sg1 type 5 Nov 26 21:50:56 ian-laptop kernel: [ 890.740008] usb 2-1: USB disconnect, address 5 Nov 26 21:51:47 ian-laptop kernel: [ 911.553875] usb 2-1: new full speed USB device using uhci_hcd and address 6 Nov 26 21:51:48 ian-laptop kernel: [ 911.601073] usb 2-1: configuration #1 chosen from 1 choice Nov 26 21:51:48 ian-laptop kernel: [ 911.664107] scsi6 : SCSI emulation for USB Mass Storage devices Nov 26 21:51:53 ian-laptop kernel: [ 913.489570] scsi 6:0:0:0: CD-ROM TSSTcorp CDDVDW SE-S224Q TS00 PQ: 0 ANSI: 0 Nov 26 21:51:53 ian-laptop kernel: [ 913.490892] scsi 6:0:0:0: Attached scsi generic sg1 type 5 This looks promising :-) Ian |
OK first mystery..

You are right the message log looks good.. but how odd that the DVD drive is showing up there, but not in the lsusb list.. Ah I see it in the lsusb output now, it's a device ID showing up with no description. A Google search of the device descriptor found the following, so we have a match. Quote:
update-usbids could you post the output of lsmod | grep usb ? trying to get a grip on why it's not showing up or automatically mounting in Linux.. Now we also know the system can see the drive.. I wonder why the EeePC is ignoring it as a boot device.. You did have a boot able CD in it when you tried choosing it to boot from right ? I had to put the CD in and close the drive let the CD spin up for a moment then boot my Netbook while the drive was already spun up, in order to get mine to boot from the External DVD Drive. If I put the CD in and let the drive go to rest, it didn't want to boot from it, or the drive wouldn't spin up fast enough for it to boot from. I though it was the crusty old drive I pulled off the shelf that caused the issue though. |
ha, success on the update-usbids:

This is interesting, and it looks like the exact problem you are having.

Thanks again for finding this.
I think that I need to change: SCSI CDROM support (BLK_DEV_SR) [N/m/?] to: SCSI CDROM support (BLK_DEV_SR) [M/m/?] In a file somewhere!!?? And then perhaps run some compilation routines? That thread seems to have died a death and the eebuntu forums don't appear to be very active. Any further guidance would be much appreciated. Ian |
That line is in the kernel configuration. You would need to change it then compile and install your custom configured kernel.

I'm kind of surprised that isn't enabled by default on a Distro that is aimed at netbooks, when none of the netbooks I have seen have Opticalkk drives.. Must have been an oversight. |
hmmm
Beyond my level of expertise at the moment and a bit scary! :-) I am reading the link that you sent and thinking that it seems like a lot of effort and risk... I thought I would change an "N" to an "M" in a file somewhere and then insmod that file? Not as easy as that? I will persevere if this is what is needed, it will do me good, just impatient to watch a DVD! :-) |
That how-to is a bit daunting, and I think it makes it look more complicate a process than it really is.. I'll look around a little for a more succinct how-to that just hits on the bare necessities.
Trouble is you can't insmod or modprobe that module until this recompile is done. I wonder if you can grab just a regular Ubuntu kernel and get this working. I don't know what changes they have made. hmmm. Ubuntu is based off Debian so the Debian Kernel Compile how-to should work just fine. I don't know why Ubuntu made that page look so intimidating. http://www.debian.org/releases/stabl...h08s06.html.en or http://kernel-handbook.alioth.debian...ommon-building and of course you will install the Ubuntu kernel source of the Ubuntu kernel you are currently running (uname -r) Once you have compiled and installed your kernel you will have multiple options in your Grub boot menu, so if your custom compiled kernel doesn't work for some reason, no harm has been done, you can always boot using the original kernel, and try again.. |
