Cool - that's even better.
Of course I first wondered... darn, where do I get the context from in
this part of my code. Then I looked at the sources of libdivecomputer...

unsigned int
dc_context_get_transports (dc_context_t *context)
{
        UNUSED(context);

        return DC_TRANSPORT_SERIAL
#if defined(HAVE_LIBUSB)
                | DC_TRANSPORT_USB
#endif
...

OK, I guess I'll just pass in a NULL pointer :-)
