Hello
les recherches pour avoir de l’aide sur ce probleme est impossible tellment le mots clef usb est devenu présent sur la toile
Ce problème a déjà été évoquer mai j’ai pas vu de solution qui semble concrète.
le problème:
c’est lent sous ma debian :
debian squeez 6.0
sous M$ meme port meme clef meme systeme de fichier vfat. c’est 10x plus rapide. 2go coier sur la clef en 7-8minute
sur ma debian ben j’attent toujours …
avec un montage a la mano:
le debit affiche environ 1,4 mio/s
Vu que sa tourne sous m$ sa ne vien pas du materiel.
voici la difference entre un dmesg avant et après le montage de la clef:
