Could be. Another possibility is that it is a mislabelled usb-storage
interface waiting for another modeswitch. Don't know if I'll bother too
much with this though. I don't think any sane person will want to use
any such weird cabled mode anyway. The Wifi interface is the only
interesting one for 99% of the users.
I only happened to get the device by accident, as an emergency
replacement for the fiber which should have been installed more than a
month ago... And then I couldn't resist playing with it :-)

Sent you off-list.
