WODIM not working with external DVD writer anymore

WODIM not working with external DVD writer anymore

I'm certain this used to work (some months ago), but I can not get WODIM
to burn a DVD from an ISO image.
I know that my DVD drive is working, and that the device assigned to it is
/dev/sr0 (I know its /dev/sr0 because "eject /dev/sr0" works)
When I try and burn an iso using the command "wodim dev=/dev/sr0 -v
image1.iso" I get the following result:
root@folio:/lib/modules# wodim dev=/dev/sr0 -v image1.iso
wodim: No write mode specified.
wodim: Assuming -tao mode.
wodim: Future versions of wodim may have different drive dependent defaults.
TOC Type: 1 = CD-ROM
scsidev: '/dev/sr0'
devname: '/dev/sr0'
scsibus: -2 target: -2 lun: -2
Linux sg driver version: 3.5.27
wodim: Success.
Cannot open SCSI driver!
For possible targets try 'wodim --devices' or 'wodim -scanbus'.
For possible transport specifiers try 'wodim dev=help'.
For IDE/ATAPI devices configuration, see the file README.ATAPI.setup from
the wodim documentation.
(If I use the command wodim dev=/dev/sr0 -dao -v image1.iso I get the same
result minus the -tao message)
wodim --devices shows nothing (Just to lines of ----)
wodim -scanbus shows

The ATA device is my SSD disk. I'd imagine that device 6,0,0 represents my
SD card reader (built into the PC). nevertheless I tried to burn using
dev=6,0,0 and it did not work - not a surprise really.
I am running the following kernel - Linux folio 3.2.0-34-generic

When I unplug and plug in the disk (and then try a burn with WODIM which
fails), syslog shows

When I put a disk in the drive udev typically does its thing, ie it mounts
a disk with data, and pops up a screen (which I can't use, it does not
offer a burn a disk option)
Anyone have any pointers to why this is not working ?
