Hi, I wrote pyduino, so this is almost certainly my fault 
Can you post the python you were using (if it isn't just the example), and any errors you're getting. I've not got my arduino with me for a few days, but last time I used it I had it working fine. One possibility is that firmata is now working at the 115200 bitrate - I need to check properly, but it's either happened or happening soon. I'm so behind with my arduino news
If thats the problem you could try changing line 51 of pyduino.py from
self.sp = serial.Serial(port, 57600, timeout=0.02)
to
self.sp = serial.Serial(port, 115200, timeout=0.02)
I'll be able to have a proper look in a few days time, but any more info would be much appreciated.
Joe
