Also try to register the different driver classes in
https://github.com/charno/subsurface/blob/android-serial-clean/android-mobile/src/org/subsurfacedivelog/mobile/AndroidSerial.java#L92.
The classes can be found at
https://github.com/mik3y/usb-serial-for-android/tree/master/usbSerialForAndroid/src/main/java/com/hoho/android/usbserial/driver.

If you have a linux computer at hand I would be interested which driver
is used by the kernel. This might give some insight if it's implemented
in usb-serial-for-android and just not registred, or if the driver is
missing.
