salut,
je suis sous sarge (même problème avec slackware et fedora), noyau 2.6.8-2-686-smp. Il semble que je ne bénéficie pas de l'usb 2.0 de ma carte mère p4p800se asus (chipset intel 865pe et intel ich5r). kinfocenter m'indique que mon scanner canonscan lide30 (qui est bien compatible usb2) n'est qu'en usb 1.1 . Et jai beau changer de ports ... ça ne modifie rien : je n'arrive jamais à me brancher sur l'usb2. L bios est bien réglé.
Comment faire pour avoir l'usb 2 ?
