    External USB CD-RW drive trouble!

    Hello, first off I would like to welcome myself to this great forum!

    Now to my issue: I just installed Slackware 10.1 (works perfectly!) but can't seem to find my external CD-RW drive. The drive is connected to a USB 2.0 PCMCIA card, I plugged in a mouse and that works okay so I know it's not the PCMCIA card. How does one go about configuring this drive in Linux? I should note that I just updated the kernel to 2.6.10.

    I did do a Google search but seem to be receiving conflicting information. Is SCSI emulation necessary with a new kernel?

    Here is the information in /etc/fstab:
    /dev/hda5 swap swap defaults 0 0
    /dev/hda2 / reiserfs defaults 1 1
    /dev/hda1 /NTFS-C ntfs umask=000 1 0
    /dev/cdrom /mnt/cdrom iso9660 noauto,owner,ro 0 0
    /dev/cd-rw /mnt/cd-rw iso9660 noauto,user,ro 0 0
    /dev/fd0 /mnt/floppy auto noauto,owner 0 0
    devpts /dev/pts devpts gid=5,mode=620 0 0
    proc /proc proc defaults 0 0
    none /sys sysfs defaults 0 0

    I added /dev/cd-rw, still nothing. I also wanted to note that /dev/cdrom is actually a dvdrom drive; however my main concern is the cd-rw drive.

    A few sites said that I should use the "cdrecord -scanbus" command. Here's that information:

    Cdrecord-Clone 2.01 (i686-pc-linux-gnu) Copyright (C) 1995-2004 Jörg Schilling
    cdrecord: Warning: Running on Linux-2.6.10
    cdrecord: There are unsettled issues with Linux-2.5 and newer.
    cdrecord: If you have unexpected problems, please try Linux-2.4 or Solaris.
    cdrecord: No such file or directory. Cannot open '/dev/pg*'. Cannot open SCSI driver.
    cdrecord: For possible targets try 'cdrecord -scanbus'.
    cdrecord: For possible transport specifiers try 'cdrecord dev=help'.

    So now I'm really confused! Any help would be appreciated!

    Check your dmesg logs - is the device recognised when plugged in? See if you get a log response when you plug it if (i.e. compare dmesg logs before and after you get). Best to start with confirming the device is actually recongnised...

    Okay, I started up Slack without the PCMCIA card and CD-RW plugged in. When I plug both in I do receive messages in dmesg. The following is the segment about the USB CD-RW:

    usb 4-2: new high speed USB device using ehci_hcd and address 2
    udev[5629]: creating device node '/dev/uba'
    uba: device 2 capacity nsec 0 bsize 512
    usbcore: registered new driver ub
