I have Iomega CD-RW ZIP 650 connected via USB port. It seems to be detected during booting (SLack 9), I can see it in "messages" (as scsi1 or something similar).
Questions :
1. What do I have to insert to fstab to mount this drive (I have also IDE DVD drive which works correctly and is already in fstab)?
2. Do I have to "modprobe" any additional modules to have my Iomega burning CD?
3. Maybe some additional options should be included in lilo.conf?
4. How to find out what is device name for it (in /dev directory)?

Any help would be appreciated as I never played with CD-RW drives under Linux.

You'd quite likely have to put /dev/scd0 as the writer,
but it depends whether it's actually being grabbed by
the ide-scsi-thing ... check
/proc/scsi/scsi
to see whether it's been picked up.

Which modules are loaded? :)

append = "hdx=ide-scsi"
should be enough.

I think that scdX or srX would be good starting points.

Cheers,
Tink

I'm having the same problem with a Cendyne CD-RW drive. Initially it was locking up the startup, but I unplugged it and after booting was completed, plugged it back in. I think it might be trying to set my HP IDE CD-RW and the Cendyne USB CD-RW to the same device. Here's the output.

How do I determine the device ID of the USB CD-RW? I looked in /proc/scsi/scsi, and only found my HP CD-RW there. Any ideas? Thanks in advance....

ok, so you have the HP Burner and another one in USB drive? Strange :P

first are you SURE it's detected and loaded? try :
cdrecord -scanbus

it should give you a list of thing detected as scsi.
If you see you burner then, look at dmesg, there should be a line about his device somewhere (or try every scsi device... not sure about scsi but I think it goes like ide : scda, scdb, scdc ...)

if it's not detected, you may have to add something to your kernel (or to load module)
Make sure usb-SOMETHING (your usb drivers, as example usb-uhci, usb-ohci... look in kernel, it's all about chipset) is loaded... type lsmod to see what module is loaded (but it'll not be showed if it's included in kernel)

oh and about lilo.conf... since usb is already emulated like scsi, I don't think you've to add something
