Are you plugging the Gryphon in before or after starting Pegasus?
I plug in first, then open pegasus, at which time it sees it, gets the drivers going, and the screen on the Gryphon then turns green.
If that's the order you're going in, try reinstalling Pegasus and drivers.
PS, set back to stock when looking for updates.
