For me the latency is not (very) important. I do not feel a lack of latency.
We tried USB converters with prolific chipset and it hangs up then, so FTDI 
chips would be better. I read also somewhere a lack of latency. May be it is 
also a question of the Kerneldriver and the driver will improve more in the 
future.
