> What it's doing is massively dangerous because it's basically performing fuzzing on the underlying device and who knows what that might trigger. Yes, this exactly. Most of the systems these chips are attached to are tiny embedded processors with very little RAM and no memory protection. It's almost a given that a non-negligible number of these systems will crash on this kind of input. The FTDI chip wouldn't even need to be in a critical signal path if it's spewing garbage all over memory.
