USB CDRW

[nitwood]

HI


I am trying to attach a usb cdrw (Iomega Predator) to my machine running Mandrake 9.0. I have just upgraded to 9.0 thinking it would make life easier.
I can't seem to find any way in which (after several reboots) the cdrw has been detected - except that the cd in it spins occasionally. I have searched the web for ideas without success. Isn't mandrake supposed to detect attached hardware and configure?

When I do lsmod, I get

I note that usb-storage is unused.
Can someone tell me how to get the machine to see the cdrw and how to tell which device it is on?


Thanks

hello,
merry christmas and welcome to ljr - the usb cdwriter uses scsi emulation, open any terminal as user root and type cdrecord -scanbus this should tell you if it is being setup properly - if it works it should look something like this:

[root@bugs root]# cdrecord -scanbus

HI

Merry Christmas to you too! It's almost over down here in Australia.
Thanks for the reply.

I tried cdrecord -scanbus and got this:



Cdrecord 1.11a32 (i586-mandrake-linux-gnu) Copyright (C) 1995-2002 Jörg Schilling

0,5,0 5) *

0,7,0 7) *


which seems to indicate that the cdrw is not being detected. I have a zip drive as well.

I'd appreciate any ideas.

Thanks

Nitwood

hello,
does usbview show anything, even an unknown device?

Does this help?

humm - just for giggles lets put a CD in the drive.
Then lets do the following in a terminal:
depmod -a
then do a rmmod usb-storage
followed by a modprobe usb-storage
then retry the cdrecord -scanbus

if this fails please post the output of ls -l /dev/ | grep sg and ls -l /dev/ | grep sd

HI

I did as you suggested and the response to cdrecord -scanbus
was:

cdrecord -scanbus
Cdrecord 1.11a32 (i586-mandrake-linux-gnu) Copyright (C) 1995-2002 Jörg Schilling
cdrecord: No such file or directory. Cannot open '/dev/pg*'. Cannot open SCSI driver.
cdrecord: For possible targets try 'cdrecord -scanbus'. Make sure you are root.


ls -l /dev/ | grep sg

gave no response

ls -l /dev/ | grep sd
gave

lr-xr-xr-x 1 root root 7 Dec 27 22:41 ptysd -> pty/m61
drwxr-xr-x 1 root root 0 Dec 27 22:42 sd/

Thanks again for your help!

Hi

I am still stuck on this problem - the results of doing the above have already been posted.

Can anyone help?


Thanks

Dude try that as root. You should get something ...

[mmiller9]

I don't know if this helps but when I connected my usb cradle pda I had to link the usb port to the cradle I.E....
as root do..

ln -s /dev/ttyUSB1 /dev/pilot (this is for the pda cd dev would be dif name)

then change owner and permissions to the user

It is just an idea sorry if it is clueless.

good luck
