T'enganxo les meves sortides als mateixos comanaments, per a que puguis
comparar. Jo tinc un ratolí USB i una cámara digital (USB-storage)
$ grep 'USB.*=[ym]' /boot/config-2.6.8.1
CONFIG_USB=y
CONFIG_USB_DEVICEFS=y
CONFIG_USB_EHCI_HCD=y
CONFIG_USB_EHCI_ROOT_HUB_TT=y
CONFIG_USB_UHCI_HCD=y
CONFIG_USB_STORAGE=y
CONFIG_USB_STORAGE_RW_DETECT=y
CONFIG_USB_STORAGE_DPCM=y
CONFIG_USB_STORAGE_SDDR09=y
CONFIG_USB_STORAGE_SDDR55=y
CONFIG_USB_HID=y
CONFIG_USB_HIDINPUT=y
CONFIG_USB_HIDDEV=y
Nota: Diria que el CONFIG_USB_UHCI_HCD=y sobra en el meu cas. Tu hauries
d'escollir entre EHCI o UHCI, en funció del processador.

A veure si et funciona. Recorda de fer les adaptacions al teu sistema.
Sort!
