Hi,
Native USB communication (used only by the Atomic Aquatics Cobalt backend) was
not yet ported to the I/O stream interface. This has now changed because I just
pushed a new USB based I/O transport implementation the libdivecomputer master
branch. This means the application is now responsible for setting up the USB I/O
stream, just like all others transports. The Atomic Aquatics Cobalt backend does
no longer open the USB device internally. Passing a NULL pointer for the
iostream will no longer work!
The advantage is that an application can now also use a custom implementation on
platforms where libusb isn't available (iOS) or doesn't work very well due to
permission problems (Android).
