here it is: 😄

> @btheye, USB interface is not that easiy to interface with the core since the STM32F103B does not come with OTG capabilities. The Serial/PS2 version will be much easier to implement!

Does the [USB host shield library](https://github.com/otelconsulting/spark-usb-host) not give OTG capabilities used with a [USB host shield](http://www.circuitsathome.com/products-page/arduino-shields) and the [Spark shield-shield](https://store.spark.io/?product=shield-shield)?

I have found a bad connection! I will fix it and let you know the results.

@kennethlimcp We have serial output! My next objective is to make the data transmission occur over WiFi - I need to do some research on the best way to to accomplish this, options being: Spark.publish, Spark.variable, TCPServer/TCPClient, or UDP. I am not too concerned about byte limits, but I will need to push the data from the Spark Core by taking an action such as scanning a barcode (as opposed to a time-driven process), does that limit my options or should I delve into each to see which fits my needs best?

Gosh, thank you! You just saved me a ton of time!
