running slackware 10 and cant get my usb cdrw to work. The system detects my cdrw that im sure coz dmesg confirms it. Hoping some1 can guide me to get it working?? (ie, be able to read and write cds with it) Thx in advance!

CD drives are usually unmounted by default. Your usb cdrom is probably located at /dev/sr0. (If not, you can find out where it's located by using the dmesg command.) So you need to type

mount /dev/dr0 /mnt/cdrom

This will mount your cdrom in the directory /mnt/cdrom. Note that you need to have a CD in the drive.

For burning, here's a tutorial. It's not great, but it should get you started:

Don't forget to post your kernel version, specially when you ask for hardware recognition problems.

Thx for replying, i still cant get it to work though. I dont really understand what the output by dmesg means so i cant determine where the location of my cdrw is.... here is the output:

Btw, when i run cdrecord -scanbus as root,

Cdrecord 2.00.3 (i686-pc-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.
cdrecord: For possible transport specifiers try 'cdrecord dev=help'.

what is happening?

oops, its 2.4.26

Can you mount CDs from your device ? If yes try to link the /dev/<device file> for your USB CD to /dev/pg0. Example if your USB CD is /dev/sd0 :
ln -s /dev/sd0 /dev/pg0

um you mean mounting cds from my cdrw device? No..... coz i dont know where the cdrw device file is..... is sd0 the default? When i try to mount a cd with sd0 it says it does not exist. Btw, juz curious, any reason to link it to /dev/pg0??

Yes from your cdrecord error :
cdrecord: No such file or directory. Cannot open '/dev/pg*'. Cannot open SCSI driver.

What is your output for :
cat /proc/scsi/scsi

And :
lsmod

i see....

this are the outputs

also, i cant find sd0 in /dev, is it sda, sdb etc??

You need to load scsi module, try :
/sbin/modprobe sd_mod

doesnt seem to work....

bash-2.05b# /sbin/modprobe sd_mod
modprobe: Can't locate module sd_mod


is this because i installed the kernel without scsi support??(all my devices are ide).

You did a kernel compile ?

What is the output for :
/sbin/modprobe -l | grep scsi

*shrug* Was trying to solve the problem by myself. Looks like i cant do it

anyway,

bash-2.05b# /sbin/modprobe -l | grep scsi

I would upgrade the kernel package to one with sr_mod scsi module or at least I would consider to recompile kernel wich is not too hard from a workable config like the one in your /boot partition.

I have not used a usb cdrw, it looks like it is wanting to use scsi emulation just like the ide drives do. Have you tried this:

mount -t iso9660 /dev/sr0 /mnt/cdrom

I would also try sr1 since the first output you posted showed scsi1
