(in that scenario the USB port works, as plugin= =20 and removing a device shows the relevant events in the console) It is random, let's say, the USB port works twice every three boots. -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" i= n the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
