CDRW X USB

Recentemente adquiri uma gaveta externa IDE/USB e coloquei um CDRW 
nela... pois bem... pra minha grata surpresa, não foi preciso de nada 
além do programa de gravação (K3B) para que o EDGY reconheça essa 
gaveta... meu problema é que eu consigo ler e até apagar o conteudo de 
um cdrw (claro que for só cdr, não vou conseguir apagar), mas o problema 
é que naum consigo é gravar cd nenhum... e o pior, não consegui nem 
identificar o erro... segue abaixo a depuração do k3b:
