What desktop was the Jessie computer running before your dist-upgrade
to Beowulf? And after? Many times desktops have their own way of
handling automounting usb devices.

The usb mountpoint as /media/usb[0-7] is contrary to the default that
udisks2 uses, namely: /media/<username>/<devicename>. Jessie may have
been using udev rules to mount usb. That's the way you automounted
external devices with Wheezy at least. Jessie came with improvements.
Check /etc/udev/rules.d to see if there is anything there. udev rules
should survive a dist-upgrade.

If there is a udev rule to automount, copying it over to your new
Beowulf computer should work.

Okay. Udisks2 is working correctly: it sees the drive; but udisks2
won't automount by itself without using a frontend utility or udev
rule.

Try mounting manually using the udisksctl "mount" command to see
if it mounts. See the udisksctl man for the details of using the mount
command.

If that works install udiskie (or set up a udev rule), start it and see
if works.

PS: There are other frontends besides udiskie. I just used it because
it was the simplest one at the time -- When I upgraded from Wheezy to
Stretch. Kept same set up when I did a clean install of Beowulf a
year ago.
