I don't think that implementing an USB command compatible clone is a
problem. The API is documented in the linux kernel ftdi_sio driver and
libftdi. The reuse of FTDI VID/PID would be.
But I doublt the usefullness. No low price cortex I know of has a build in
high speed YSB phy, and implementing something like synchronous FIFO will be
hard.
