Stacey Sheldon	e16be98224	usb cdc: ensure com buffer is drained when no DTE is attached ... The CDC layer on F1, F3 and F4 now always acts like an infinte data sink whenever *either* there is no DTE present (ie. no terminal program listening) *or* the USB cable is disconnected. F1 and F4 were previously checking the cable but not the DTE. F3 didn't check anything. The COM layer didn't even ask the lower layers. All of this used to mean that any time a caller did a blocking send to a CDC device without a DTE, it would eventually block for up to a 5s timeout waiting for space in the Tx buffer.
