I just tested it with hardy beta + all updates, still doesn't work.
uname -a
Linux studioblaster 2.6.24-16-rt #1 SMP PREEMPT RT Thu Apr 10 15:15:40 UTC 2008 i686 GNU/Linux

cat /dev/ttyUSB0 doesn't return any output, with sudo it gives Input/output error.

dmesg attached. The last few lines are interesting:

SqRt7744: Does this device (DeLORME LT-20) still not work in Hardy?

You can test this in the live environment of the Desktop CD for Hardy.
It would help us greatly if you could test with it so we can work on
getting it fixed in the actively developed release. You can find out
more about the development release at http://www.ubuntu.com/testing/

Thanks!
