Hi everybody
I'm having problems with my cd recorder. It seems that it is not being recognized by my Fedora Core 1. I've recently upgraded the kernel from 2.4.22-1.2115 to 2.4.22-1.2174 and I don't know if that the reason of this problems. I remember when I had just installed the system it was functioning, in fact the GnomeToaster I've used still has the recorder in preferences, It shows as ZIP CD650 USB, in /dev/scd0.
This is the output of dmesg:

I've been a whole week reading the forum and google, but I coudn't find any help for my case. I'm sorry if I'm too extense, but I think this might help you to help ME
Please if you know a way to solve this problem, be as explicit as you can, I'm a linux Newbie, so I don't understand many basic things.

Greeting from Argentina.

Is this the entire output of dmesg? I don't see any messages that the OS is detecting anything USB.

Does lsmod show any USB modules loading?

I think that's the problem, what should I do if there's no USBhere the output of lsmod:

Sorry, I hit a magic button

I've loaded the modules of usb and shows like this in lsmod

and in dmesg

I've added in /etc/rc.d/rc.local this line modprobe usb-storage

What should I do now?
