If my guess stated above is correct, yes.
Let's look at this way - with Jellybean and no sd card, gone are the days of a selection for charge only or usb mass storage mode.
That basically leaves only the default media sync/transfer mode when the data lines go hot.
When the software doesn’t get the answer from the computer that it needs, then its only choices would be a lockout or a debugging connection.
Clearly seems to be choosing the latter.
