Thanks Jonas, Pablo and James

I answer all your queries and give the outputs of your suggestions

Anyway, thanks ... I feel I'm moving forward a little.

Sorry Jonas,

I guess just about everything uses a USB port these days ... I meant
the USB ports for my jump/thumb/flash drive.

Ok... that gives:

$ lsusb

Bus 002 Device 002: ID 413c:2003 Dell Computer Corp. Keyboard

Ok ... I removed the file (I took a copy and put in my home directory where
the system wouldn't find it) and rebooted ... but it regenerated the file
exactly the same and I still can't see either the dvd or jump drive mounted
under /media when I insert a DVD or the jump drive ... but given the
correct info of the lsusb command, I'm supposing that's because the hardy
upgrade has screwed up the /dev symlinks, which is why you were asking
for those.

Doing this, I see when I insert the jump drive:

When I insert a DVD it spins up and after a while gives the message in
/var/log/messages:

I did:

$ sudo mount /dev/cdrom -t iso9660 /mnt
mount: block device /dev/scd0 is write-protected, mounting read-only
$ ls /mnt
bu-boot-2-2-9.tgz ...

Suffice it to say that worked ok. So I can at least read DVDs that way
if necessary.

So what should the symlinks be to make my DVD and jump drive appear under
/media as they used to with gutsy?

Thanks again for all the help so far.
