Bonjour Le Forum Fedora ;
Même problème ici, avec un seul matériel : un adaptateur disque sata / usb3.
Celui ci fonctionnait parfaitement jusqu'au 3.10, et depuis udev "refuse" de créer le device (ne le créeait pas). En faisant un mknod b à la main, je peux ensuite monter mon périphérique, mais ce n'est pas le comportement attendu :-/
Voici la description des matériels incriminés :

A noter que le matériel est fonctionnel sur un 3.10 compilé maison, mais pas sur un 3.10 fedora. A noter qu'il n'y a pas de différence sur ces matériels dans les choix de compilation (ce qui indiquerait peut être un patch appliqué en avance de phase ? je n'ai pas "vérifié" (regardé, simplement) ce point). A noter enfin que ça ne fonctionne plus du tout depuis le 3.10.4 (compilé vanille ou noyau fedora). Et que ce matériel continue de parfaitement fonctionner en bootant sur un 3.10 (ou en faisant un mknod b)
???
Mon premier vrai bug en 7 ans de fedora, ça vaut bien un petit trait d'humour pour finir : et dire que "linux est le premier a supporter usb3" (dixit ouatmilles ans).. et *paf* certains usb3 ...
