It's possible that the WiFi controller is connected internally by USB. I seem to remember another post where a user said his app could see a Ralink device which I would assume to be his WiFi controller. I would have thought that Android shouldn't expose such internal devices to an app but it seemed to in his case.

If this is the case, and it is the first device in the device list, then I can see potential problems as, for simplicity, UsbSerial assumes that the first device it sees is the one of interest. This is true in almost all cases and making the assumption avoids some messy complications in coding for a situation that will seldom arise.
