Both motu seems to work fine, Motu audio setup and software recognise them and you can change clock and all settings without any prob.. so this is the weird part ... when i open Cubase 5.1 ( i have tried sx3 and some other versions with same results) and choose Motu ASIO in device setup and press "ok" cubase crash without any error.. it just close.. sometimes it dosent even open again .. it crash at the Cubase splash screen..
i have tried usb connection as well and i have checked with an old driver (Cd driver) and the latest from the download section.. i also have tried windows xp 32bit but no luck ...

Any ideas??
thanks in advance cheers
