/dev/disk/by-id and usb connections

Hi everybody,

My SSD connected via a USB 3 and eSATA box (brand AKASA) is recognized
differently by Wily compared to 14.04.2 LTS and other previous versions
of Lubuntu (all Ubuntu family flavours).

When connected via USB 2 as well as USB 3 ports in the computer, Wily
will recognize it as an ata drive as well as wwn drive (whatever that
means).

When connected in the same way, 14.04.2 LTS and other previous versions
will recognize it as a USB drive.

See the attached file, containing the output of the commands

lsb_release -a
uname -a
ls -l /dev/disk/by-id

for both versions of Lubuntu.

I think it can be an improvement, but it might also create surprises in
software that is not 'aware' of the change.

Can *you* explain why and how this has been changed?

Best regards
Nio
