as far as I know there's no USB command the read out how many bytes are still
in the internal buffer of the chip.
The D2XX library uses a background thread to constantly read all available data
into a memory buffer on the host. That's the reason it can tell you how many
bytes are in the buffer ;) At least that's my current knowledge about it.
