Of course first I tried dmesg, and had to go through lots of output until the last lines said it is indeed ttyUSB0. Then I tried 'ls /dev/tty*' and there it was too. So I am on my way (I hope)...
One of the really nifty tools (part of coreutils) is 'tail'. The output of dmesg (or the contents of /var/log/messages) is often large (and generally of no interest to the task at hand) and very often the info you want is in the last few lines (eg the blather generated by the Hotplug code), so it is useful to do:
% dmesg|tail
OR
% tail /var/log/messages
to get this information.
Or use 'less' for something a little more interactive: dmesg |less then you can use all the vi-style motion and search commands like G - go to end b - backwards page ?pattern<enter> - search backwards etc.
