[mc1322x] Contiki hello-world example

This is very weird... It's finally an USB-related problem.
The problem is reproduced only on my Ubuntu 8.04 machine. On this PC,
small bin images (blink-green ) can be uploaded without problems via
mc1322x-load.pl. However, bigger images like the contiki examples seem
to return "done sending files" earlier than expected.
On my laptop, under Ubuntu 9.10 and 10.04 both "hello-world" and
"blink" contiki examples can be loaded into the econotag through
serial just fine.
As the binaries are the same, I think that the problem is in that
Ubuntu 8.04 uses libusb0 instead of libusb1 so perhaps there is a
limited support for the FT2232H IC. libusb0 is also incompatible with
OpenOCD so I can not use the JTAG interface on the 8.04 PC either.
Has anyone shortcut this limitation on 8.XX Ubuntu versions?
Thanks!
Daniel.
