Error connecting to Arduino

[Andy Irving]

I am having problems connecting to the Arduino.  I have an Uno connected on COM5 and have uploaded the StandardFirmata sketch.

Here is the message in the Flash console.

connecting to localhost Hub for storing/retrieveing parameters...

--->initializing parameters from file <localhost:Untitled-1.xml>

Widget 'input0' connecting...

...input0 ERROR CONNECTING ---> IS THE DEVICE CONNECTED?

/service/arduino/reader-writer/connect FAIL {java.lang.RuntimeException: Error inside Serial.<init>()}

Here is the message from hub.

If anyone can point me in the right direction it would be much appreciated.

Things look okay from what I can see - a few things to check:

• If the Arduino software is still running, it may own the serial port preventing the Hub from connecting - don't run the Arduino software and the Hub at the same time
• Try rebooting the computer and trying again in case the serial port has a problem
• Are the Arduino LEDs showing that it has power?

Let me know if you have any other info.
