Can't download with r204

[Maxxer]

Hi. I've just bought a GH615 but I cannot get it to work on Ubuntu
Intrepid.

I manage to install the requirements (like CherryPy 3.1) but still i'm
having troubles using both console and gui.
when trying to fetch all tracks via console I get this:

=>c
Export all tracks
FYI: Exporting to default format 'gpx' (see config.ini)
Traceback (most recent call last):
File "gh600_console.py", line 270, in <module>

_querySerial
raise GH600SerialException
gh600.GH600SerialException: <gh600.GH600SerialException instance at
0x89d3e0c>


trying to use gui I get this on the browser:
