+// device_io_dummy
+// Main goal of device_io_dummy is to emulate a hw::io::device_io without the need to actually
+// connect a device.
+// Many operating systems do not support giving raw USB access to a process (android), or don't
+// support that at all (hi iOS), therefore other means of connection can be used, either USB
+// abstraction provided by the OS (monerujo), or BLE (also monerujo).
+// Monerujo implementation is written in Java, which makes it a nice fit for iOS, but makes the
+// code extremely unportable, so for this reason the code in here is written in CPP.
+// Data transport is made available in wallet2_api.h, so wallet developers can easily plug their
+// own USB/BLE/other transport layer.
