The behaviour of the ftdi_read_data function is not so well defined
(IMO, no offense intended). It loops calling usb_bulk_read(), collects
all the data, until the requested number of bytes have been transfered;
but it also returns when the usb_bulk_read() call didn't return any
data.
For my application, I would prefer the behaviour of the original FTDI
d2xx dll: the read() call returns when either the requested number of
bytes have been transferred or when the read-timeout has expired.
Here is a patch which implements a ftdi_read_data_timeout() function
that also has this behaviour. The patch only works on Windows since
it GetTickCount() api call.
Is it worth to consider this extension for the official repository?
Thanks,
Thomas
