I have a new Utrabook with 8.1.
No problems with Ascom but with the Starshoot Autoguider and PHD.
No driver from Orion for USB3!
I had to revert to the old Netbook for the Guiding.
I use a Keyspan USB converter and connect to the Handcontroller.
It took days to get Windows going, between mutiple Win ub-date, Sony-update and re-installing and
Starrynight re-registering etc.
