does someone know if there is a debug dll for FTDI D2XX ? I want to trace every call and every data packet which is exchanged over the DLL. There was something for CAPI (ISDN) long time ago, which i think should also work for D2XX. The original DLL was renamed and a new DLL was created which was just a wrapper and calls the original functions of the renamed DLL.
Is such a thing existing ? Or is there meanwhile a general way of doing this ?
By the way: Is there any software USB sniffer which is able to trace USB communication between FTDI D2XX driver and FTDI chip itself ? Or is there even a description of the communication protocol itself ?
