[PD] pduino-arduino trouble

[Max Neupert]

it's really hard to fix since it simply works sometimes and then  
stops working.
not very reliable for an installation supposed to run automatically  
in a different city for some weeks :(

this is the output when it does work:

----------
error: [comport] ** ERROR ** could not open device /dev/tty.Roy-Dial- 
upNetworking-2:
  failure(16): Resource busy

[comport] invalid handle for /dev/tty.*
[arduino]: version_0.3
get_baud_ratebits: 57600.000000
set_baudrate baudbits: 57600
[comport] opened serial line device 5 (/dev/tty.usbserial-A6004nvF)

Arduino/Firmata_version: 1 0
----------

this is the output when it doesn't:

----------
error: [comport] ** ERROR ** could not open device /dev/tty.Roy-Dial- 
upNetworking-2:
  failure(16): Resource busy

[comport] invalid handle for /dev/tty.*
[arduino]: version_0.4
get_baud_ratebits: 115200.000000
set_baudrate baudbits: 115200
[comport] opened serial line device 5 (/dev/tty.usbserial-A6004nvF)

UNKNOWN_INPUT_COMMAND: 6 0
-----------

so it'a exactly the same, first the wrong device gets opened because  
of the default name, but then one tim it can connect, the other time  
it can't.

anyone has a clue what's going on?
