Has anyone ever seen a situation where on a Macbook air using an external Apple USB superdrive that the Bootcamp Assistant doesn't recognize the drive is present? It's one of those matching model A1379 units that Apple sells as an optical reader/burner for a Macbook Air. Under the apple menu under "about this Macintosh" and in the "system report" the USB subhead shows that it sees the drive - you can even see the CD show up on the desktop with the windows install media on it. But the bootcamp assistant claims there's no drive attached when we attempt to install windows. The CD is good since it works on all the I.T. windows machines we have onsite. Ideas?
