I am using a USB2.0 device connected to the port directly on the back of the iMac.
The device is a Pinnacle DVC120 and it does get recognized by Win7 when I activate/connect it in the USB list.
I am using the Vista drivers that were recognized by the GuestOS/Win7 inside Parallels but when I start Studio14 it does not get recognized by Studio14, it doesn't show up in the list of possible/other devices either.
I found out in the Studio14 (Avid-site, their support site) support pages that the list of supported devices in Studio14 is lacking the DVC120.
I have a request open now with Pinnacle if this is true and that I have to buy a new device just because I moved to Win7.
To make a long story short....the Parallels problem is solved (although Studio 14 and 12 still whine about the display driver that is not recognized), it does not crash anymore but now I have a useless Studio14 package and am out of the upgrade fee of $300.- or so.
Ah well, a hobby is a hobby and hobbies cost money, too bad.
Anyway, I will use XP and Studio12 again, pity...no HD...
