Summary0000928: USB stick not detected during boot
DescriptionUSB stick is not always detected during boot process. This makes starting of an autoscript file from a USB stick impossible.
Steps To ReproducePlug in USB stick in default U-Boot configuration. Autoload tries to detect USB stick but does not find it.
Additional InformationThe S3C64XX USB-Root-Hub reports in its descriptor that it needs 4ms from power-on to power-good. However this value seems far too little. We need at least 150ms.
