[USB] Conflit IRQ

[Jérémy Vies]

Pour ceux qui ne voient pas l'interêt de déplacer la carte:
=> toutes les irq ne sont pas disponibles sur tous les ports pci...
donc quand on a un problème d'irq, soit on tente de le forcer dans le 
bios (s'il supporte ça), soit on essaye de changer la carte de port pci...

Elle est pas belle l'architecture PC :)
