WS281XPlugin not working

[jamiechapmanbrn]

Adding an Arduino device with the WS281X plugin is not working. When I add a device instead of success I see the following error:

System.AggregateException: One or more errors occurred. (RGB.NET threw exception: The I/O operation has been aborted because of either a thread exit or an application request.)

It doesn't happen if I don't add it on a com port that doesn't do anything, Eg an unconnected COM1 instead of the arduino device on COM4.

If I subsequently attempt to add the device, I will see an error indicating that it cannot access COM4 (as it is probably still in use from the prior crash).
