Latencies are also much lower and more predicatable than USB because these are dedicated interfaces This can't be stressed enough. The article is all raving about speed, but completely ignoring latency. Which is at least one of the reasons why USB hasn't completely replaced the other most common ports. USB only replaced ports for basic consumer devices without much special requirements in the timing department (and don't get me wrong, it did that in a fabulous way, the 'u' in the name was a good choice) The most common usb-serial converter from FTDI does not have a completely predictable latency (mainly due to the software stack if I'm not mistaken) which can make it a pain to use with serial device which can only continuously stream data: small buffer size = no go. Likewise, up until now, we still have some software using the parallel port because it's a readily avaiable GPIO with predictable sub-mSec latency, on Windows. USB doesn't even come close to replacing that, so we're switching to dedicated DAQ hardware.
