Ei llista,

activem el debug en els moduls de usb

# modinfo usb-storage
parm:           delay_use:seconds to delay before using a new device (uint)
# modinfo usbcore
parm:           usbfs_snoop:true to log all usbfs traffic (bool)
parm:           blinkenlights:true to cycle leds on hubs (bool)
parm:           old_scheme_first:start with the old device initialization 
scheme (bool)
parm:           use_both_schemes:try the other device initialization scheme if 
the first one fails (bool)
parm:           autosuspend:default autosuspend delay (int)

creariem un fitxer nou 
/etc/modprobe.d/00custom-alias

amb les linies:
#******
options usb-storage delay_use=30
options usbcore usbfs_snoop:true old_scheme_first:true use_both_schemes:true
#******

si els moduls usb son inclosos al initrd pot ser necessari actualitzar-lo
(segurament hi son)

# update-initramfs -?
Usage: /usr/sbin/update-initramfs [OPTION]...

Options:
 -k [version]   Specify kernel version or 'all'
 -c             Create a new initramfs
 -u             Update an existing initramfs
 -d             Remove an existing initramfs
 -t             Take over a custom initramfs with this one
 -b             Set alternate boot directory
 -v             Be verbose
 -h             This message

executar
# update-initramfs -u -k `uname -r`
(o alguna cosa per l'estil)

tornar a arrancar i estudiar el dmesg per les anotacions de usb.

Salut,

Jordi Pujol
