What I meant was the new "autosuspend" parameter of the "usbcore":
[EMAIL PROTECTED]:~$ modinfo usbcore
filename:
/lib/modules/2.6.21-rc6-mm1-mactel/kernel/drivers/usb/core/usbcore.ko
license: GPL
vermagic: 2.6.21-rc6-mm1-mactel SMP preempt mod_unload CORE2
parm: usbfs_snoop:true to log all usbfs traffic (bool)
parm: use_both_schemes:try the other device initialization scheme if
the first one fails (bool)
parm: old_scheme_first:start with the old device initialization
scheme (bool)
parm: blinkenlights:true to cycle leds on hubs (bool)
parm: autosuspend:default autosuspend delay (int)
