probleme configuration speedtouch

comme le sugere le titre, je bloque sur l'install de mon modem speed touch usb...

voici la procedure suivit...

d'abord recuperation des drivers speedtouch-amd64 (ceci)

n'etant disponible que pour mdk, je transforme le drivers avec alien puis j'install...

#dpkg -i speedtouch_amd64.deb

--------

ensuite recuperation du firmware ici...

decompression dans le home du root puis copie du fichier mgmt.o dans /usr/share/sppedtouch/...

--------

# modem_run -m -f /usr/share/speedtouch/mgmt.o

finalement utilisation de

#adsl-conf-pppd

pour configurer la connection...puis

pon adsl

et

plog  -f

me renvoie lkes log suivant :
