A typo for what?

It's a list of device drivers for USB connected audio devices - i.e. Explorer 1/2, IE50, 800 series USB input, Prime, Translator, etc...

What have Meridian made with USB connections that could have been mistaken for this?

I thought the AC600 in an earlier version of the drivers might have been a type, but that got removed from the list with a recent release.
