USB ne fonctionne que lors du démarrage en mode de récupération
J'ai Ubuntu 14.04 LTS 64 Bit installé sur ma tablette Windows HP Pavilion avec un processeur Intel® Core ™ i3-4030U à 1,90 GHz × 4. Lorsque j'ai démarré Ubuntu, ma souris USB ne fonctionne pas. Le laser s'allume pendant le processus de démarrage, mais lorsque l'écran de connexion apparaît, il s'éteint. J'ai pensé que c'était apparemment un problème avec les périphériques USB car lorsque je branche ma clé USB, le lecteur n'apparaît pas et je n'ai que des sda dans mon dossier/dev /. Habituellement, je dois redémarrer plusieurs fois pour que les périphériques USB fonctionnent. Qu'est-ce qui pourrait causer ce problème?
Voici ce que lsusb génère lorsque les ports USB ne fonctionnent pas:
stefan@stefan-HP-Pavilion-13-x360-PC:~$ lsusb
Bus 001 Device 002: ID 8087:8000 Intel Corp.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 003 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
J'ai redémarré le système et maintenant l'USB fonctionne. Voici la sortie de lsusb:
stefan@stefan-HP-Pavilion-13-x360-PC:~$ lsusb

Sur le bus 003 périphérique 002, la ligne vierge est destinée à un périphérique mémoire USB. Sur le bus 002, le périphérique 002 contient la souris optique.
Edit: J'ai découvert que l'USB fonctionne à chaque démarrage du système en démarrant d'abord le mode de récupération dans GRUB, puis en sélectionnant "reprendre" dans le menu. Mais l'USB ne fonctionne jamais lorsque je démarre régulièrement le système.
Voici la sortie de dmesg | grep usb avec USB fonctionnant après le démarrage normalement:

Edit (25/08/15): J'ai découvert un phénomène intéressant. Chaque fois que je démarre Windows 8 (où l'USB ne pose aucun problème), je redémarre et sélectionne Ubuntu dans le menu GRUB, cela fonctionne soudainement. Comment un USB fonctionnel sous Windows peut-il le faire fonctionner) correctement après le redémarrage dans Ubuntu?
D'accord, le problème a été résolu en passant à la dernière version d'Ubuntu (15.10 Wily). J'ai également supprimé Windows de mon ordinateur portable lorsque j'ai installé Wily, il s'agit donc maintenant d'un système à démarrage unique, si cela était lié au problème. Dans Ubuntu Wily, je n'ai jusqu'à présent découvert aucun problème.
