Cannot upload Blink Sketch to new Esplora (Mac)

[MisterG]

have a new Esplora board and IDE v1.0.5
I have selected the Blink Sketch and tried to upload it. But I get a message about being unable to upload to a Leonardo on the selected port. I understand the Esplora is based on the Leonardo so I followed the instructions about pressing the reset button first. The "On" and "L" LEDs light up, but no Tx/Rx

I checked the port is active by switching to the Uno (rev2) and using the blink sketch on that. No problems.

Please can anyone give me some advice?

(I have also posted this in the Arduino.cc forums, so don't worry if nobody can help!)

Thanks in advance

Which version of Arduino development environment are you using? If you are using 1.05 there should be a board option for the Esplora so you shouldn't have to select Leonardo. I don't think selecting Leonardo as board type will matter but if you don't see an Esplora option it may suggest you have an older version of the development environment. If this doesn't resolve the problem could you let me know what version of development environment you are using, what if any error messages you are seeing and confirm that you are seeing a serial (or usbmodem) port associated with the board. Also when the board isn't being programmed does the L LED blink rapidly?

I feel so stupid. After hours of research and faffing about I went to play with the RaspPi, trying to use SSH or VNC. This tied up the USB lead I was using.

"I'll have one last try", I thought, and grabbed the cable for my Kindle. Up popped the message about an unrecognised keyboard being connected. Off to load Arduino IDE (1.0.5) and everything is working.

Moral of the story - check the cable!
