ERREUR pas de place sur la bague ep avec un périphérique USB 3.0

Je viens de faire une nouvelle installation de mythbuntu 12.04 hier sur une toute nouvelle machine. ASRock Z77 Extreme4 avec jeu de puces vidéo Intel, 8 Go de RAM.

Je vois des références google à cela comme un problème USB 3 dans ce pilote mais comme je l’utilise en stock 12.04, je voulais au moins avoir un ref bug pour Ubuntu.

Le dmesg entier est rempli avec:

[22822.772021] xhci_hcd 0000:00:14.0: ERROR no room on ep ring
[22822.772024] xhci_hcd 0000:00:14.0: ERROR no room on ep ring

Je ne suis confronté à ce problème que pour la deuxième journée consécutive sans rien changer à ma configuration de périphériques USB, qui fonctionnent correctement depuis des mois. J'ai trouvé que redémarrer l'USB m'aide dans mon cas à ce que mes périphériques soient à nouveau détectés par le noyau.

Déterminez les adresses de vos contrôleurs:

lspci | grep USB
00:14.0 USB controller: Intel Corporation 8 Series/C220 Series Chipset Family USB xHCI (rev 05)
00:1a.0 USB controller: Intel Corporation 8 Series/C220 Series Chipset Family USB EHCI #2 (rev 05)
00:1d.0 USB controller: Intel Corporation 8 Series/C220 Series Chipset Family USB EHCI #1 (rev 05)

Dans ce cas, il s'agit de 00:14.0, 00:1a.0 et 00:1d.0. A vous d'être différent.

Dissociez et reliez chaque contrôleur via son adresse:

echo -n "0000:00:14.0" | Sudo tee /sys/bus/pci/drivers/xhci_hcd/unbind
echo -n "0000:00:14.0" | Sudo tee /sys/bus/pci/drivers/xhci_hcd/bind

Dans mon cas, le faire juste pour le contrôleur xHCI était suffisant et tous les périphériques sont à nouveau apparus dans lsusb. Au cours de mon analyse, j'ai débranché presque tous les périphériques USB et mis sous tension les périphériques dotés d'une alimentation externe, ce que je recommande dans de tels cas.

De toute évidence, étant donné que l’USB ne fonctionne pas et que tous vos périphériques d’entrée sont probablement USB, vous avez besoin d’un type d’accès distant, tel que SSH.

Au fur et à mesure que vous écrivez, xhci_hcd est le module du noyau (pilote) pour USB 3.0 et semble causer des problèmes similaires sur d'autres systèmes. Peut-être devriez-vous déposer un rapport de bogue, car je ne vois pas de question dans ce que vous avez posté ici.
