Finally catching up with my backlog. An alternative would be to have all the stream start code placed under the vb2 start_streaming callback, symmetrically to what the driver already does with streamoff/stop_streaming. That would eliminate the need to export the symbol from the vb2 framework. Have you considered that option? Best regards, Tomasz
