Which kernel version are you using on the Origen? I noticed the same problem a while back, but it appears to have been fixed in the Samsung landing team tree. There is still another bug present in the Origen kernel preventing USB-ethernet working with EHCI. Some patches have been posted, but they have not made it into the trees yet. Search the mailing lists for s5p usb burst to find them. -- Mans Rullgard / mru _______________________________________________ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev
