I've been using Master Emulator API 2.1.3 in Visual Studio 2010 Express, and have spotted a fix I may need in 2.1.5 so I've switched to using the 2.1.7 API. However, I've got an issue creating a new Master Emulator object, with gcnew throwing "'type' object has no attribute 'HCI_SPI_PROTOCOL_CMD'".
