Je branche le cable à  l'ordi et déjà  j'ai pas de détection ni rien , je sais pas si c'est normal

" Msg: DhaHelper driver and/or library not found.
Cause: the driver may have been not started yet; it may have been uninstalled; the library has been installed without administrator privileges. "

--------------------------------------------------------------------------------
ParallelLink cable
--------------------------------------------------------------------------------

The node is '/dev/parportX". You must have r/w permissions on this device, and
the device must not be locked exclusively by any other parallel port driver
(such as some CUPS drivers for parallel port printers) - otherwise libticables2
won't be able to acquire and use the port.
This can be done by:
- giving up r/w permissions to others (chmod ugo+rw /dev/parport?) or, better,
- adding your user to the group 'lp' (edit /etc/group and add your
username after the ':').
Example 1:
crw-rw-rw- 1 root lp 99, 0 2005-02-26 07:39 parport0
Example 2:
lp:x:7:romain
- On some distributions (e.g. Fedora 12), an alternative, groupless setup
detailed in the last section can also be used.

If you have a parallel port printer, for libticables2 to work, you may need to
stop the CUPS printing service (the way to do this depends on your distribution)
and unload the 'lp' kernel module (`rmmod lp` as root), so as to liberate the
exclusive lock on the parallel port held by CUPS / the printer driver.

sudo chmod ugo+rw /dev/ttyS0

Msg: timeout occured while reading to the device.
Cause: check that link cable is plugged and/or the calculator is ready.
