LiteOn DH-20A3H does not read or write to media after firmware update

I am hoping somone can help me as i have a strange problem and cannot seem to find a solution.

I have just updated the firmware on my DH-20A3H to YP5W using the official firmware from the LiteOn site and after the required reboot the drive no longer reads or writes to any media, the LightScribe still works OK and it detects the LightScribe surface every time.

When i insert a CD/DVD it doesn’t even check the disc type, all info programs show no media insterted. I am not sure if this is a firmware issue or a drive issue, any guidance would be most apprecaited.
