Graver "K3b did not find a suitable writer&qu

Salut, j'ai un problème, quand je lance k3b writer sous knoppix, il me dit celà quand je click sur "burn" (après avoir selectionné ce que je voulai graver).
Il reconnait tout mes lecteur, mais apparement il reconnai pas mon graveur oO ?
C'est bien ca le problème ?

je suis sur knoppix 8.1, sur Linux-2.6.11.
J'ai ésayé "cdrecord -scanbus et cdrecord -scanbus dev=ATAPI"
Sa m'affiche :
