I'll take a look and see what I can find. You could also write an
Arduino firmware using Firmata as a library, then just support the
things you need to have working. Perhaps the timing of the analogIns
or something like that are interfering.
Look at the examples in Arduino, like SimpleDigitalFirmata. They are
in File -> Sketchbook -> examples -> Library-Firmata
