It appears to have a broken layer board as any stress on the connector makes it randomly stop working, but with enough gentle wiggling and then NOT TOUCHING I was able to do my first FTDI download from Subsurface-mobile on Android.

The app is opened with a intent, because we declare that we would like
one:
<intent-filter>
	<action android:name="android.hardware.usb.action.USB_DEVICE_ATTACHED" />
</intent-filter>


How to receive that in Qt and open the right Qml screen, I have no clue.


I would also like us to not just print "FTDI" in the drop down. It would
be way better to say bus / device number, and some other relevant
strings. We could also use this to open the right device, not just some
device that we might find. This makes it more inline with now the
Bluetooth thingie works.
