I'm having a similar problem.
I'm using Arduino 0017, an Arduino Mega and i'm on a Mac Book Pro running OS X 10.6.
I can upload sketches in the normal way via the Arduino without any problems.
I've changed the baud rate via the serial monitor to 9600.
I've made sure that the StandardFirmata file in the Arduino environment say: 'Firmata.begin(5331);' - which is the same in the serproxy.cfg
I've also made sure that the serproxy.cfg says 'comm_baud=9600'
When i run the Flash test fla i get the following: Socket connected! Socket closed!
Here's what i get initially in the Terminal:

macbookpro:~ me$ /Users/me/Desktop/Arduino\ exp/as3glue-cs247-01/as3glue/applications/Serproxy-0.1.3-3/serproxy ; exit;
Serproxy - (C)1999 Stefano Busti, (C)2005 David A. Mellis - Waiting for clients
When the Flash is run i get this message from the Terminal:
'Failed to open comm port - connection refused'
Here's the config for the Serproxy:
# Config file for serproxy
# Do not Transform newlines coming from the serial port into nils
# Comm ports used
# Default settings
# Idle time out in seconds
# Port 1 settings (ttyS0)
# Port 2 settings (ttyS1)
# Port 3 settings (ttyS2)
# Port 4 settings (ttyS3)
I'm also unclear how i would go about identifying what the port number is for the usb.
Can anyone help? :'(
