Esplora Uploading Problem

I am taking a look at the Arduino Esplora but having problems with the uploader. I plug the device into my USB hub and it assigns COM40. When I compile and upload, it disconnects from Port 40, connects to port 41 and does the upload on Port 41. 

The Serial monitor remains connected to Port 40, but no output is written to this port. Port 41 does not show up in the Port Selection DDLs.

I have seen this pattern when I selected Com38. It wrote to Com39. 

I am using the Arduino Esplora loader. 

Is there a configuration option I am missing? How do I get it to upload to the same port that I selected?

Verbose build output is attached.

This is a feature of usb aware arduino boards. For upload they require to be forced into upload mode. In this mode the processor starts on a different port. The "force/reset" happens by connecting to the chip at 1200 baud serial. The hardware definition of the board tells Visual Micro when this is needed it is not something you van change.

Using the arduino ide, you should see the same system happening.

Usb hubs can cause usb issues with some boards, it's well documented.
