Unable to find CMSIS-DAP device

I am on Windows 10 and Python 2.7 using PlatformIO version 3.5 and am trying to download a simple blink example to an RFDuino board.

When I run “pio run --verbose --target upload” I get the following output:

[12/30/17 15:34:22] Processing rfduino (platform: nordicnrf51; board: rfduino; framework: arduino)

I have a valid COM port. But I havent been able to find any information on what to do to get the RFDuino to be seen as a CMSIS-DAP device.

I would appreciate any help you can provide for me to be able to start downloading code to this board.
