	I've inspected the log. The only difference I can see with a 'reference' run 
here is that the hack used to reset the AFE isn't trigger here. Since I 
believe this issues are related to powersaving, could check if your linux 
kernel has been built with CONFIG_USB_SUSPEND=y ? The config file used to 
build kernel is often stored in /boot.
	I configured my kernel without it. It may be the difference.
