援引上面提到的英文文章，请注意以下内容，特别是前几句：
According to our tests motherboards with Intel's i815, VIA's KT133 and 694 chipset also operate problem-free at low latency with USB active. With all this in mind the subject USB can get an 'all clear signal' from our side, because all newer computers don't have any problem, and older ones can be updated for a few bucks, or be used with un-critical USB hardware. Please note that this signal/statement is only valid for the combination RME products, low latency audio and USB MIDI interfaces!
同时请注意此文的时间，乃是2001。彼时USB方兴未艾，2.0还没出来。文中提到的BX、815、694主板，不知诸位大侠还有印象否。
多的话俺就不说了。人家老外都说了。
