Yamaha Steinberg USB driver version 1.9.9


I have a CI1. I can’t find where to download the Yamaha Steinberg USB driver version 1.9.9, even though this page http://www.steinberg.net/en/newsandevents/news/newsdetail/article/new-tools-updates-for-selected-audio-interfaces-3792.html says it has been 'previously released.

Neither is it here http://www.steinberg.net/index.php?id=12354&L=1

I know that the CI1 isn’t supported anymore, but I’m guessing that the USB driver update still applies?
