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.
