Can't see CD-Rom anymore

Well, this is embarrassing. My CD-ROM has disappeared.

Any suggestion would help. I’m not command prompt very savvy, but happy to learn. Thanks!

Check if the kernel module is loaded:

lsmod | grep sr_mod

If no output, try loading it manually:

sudo modprobe sr_mod

See if the device shows up.


Tried it and no output.

Manually loaded and it gave me this message: libkmod: kmod_config_parse: /etc/modprobe.d/usbcore.conf line 2: ignoring bad line starting with ‘mw’

I’m guessing I need to look into usbcore.conf and see what that offending ‘mw’ is?

Thanks for your help

I removed the ‘mw’ from usbcore.conf and typed lsmod | grep sr_mod yielded

sr_mod                 28672  0
cdrom                  86016  1 sr_mod

I still don’t see the drive. K3B can’t find it either.

The only thing inside usbcore.conf is: options usbcore autosuspend=-1 #prevent USB auto-suspend for new USB devices
