Hi All,
I need to provide the USB connectivity for USB not capable microcontroller. The FTDI chips are the simplest and cheap solution. However the VCP drivers do not provide sufficient throughput. The D2XX do not, but they are not open source, so are usable only for a few platforms, for which FTDI has provided binaries of their library. Is there any Open Source equivalent of the D2XX drivers? Has anybody succeeded to reverse engineer the USB protocol used by the D2XX drivers?
