There are many cases where plugging the interface into one port will work, but using different USB port results in much worse performance. This has been seen even on Apple systems.</dd>\r

+ main "bus" inside the computer. Some laptops (and possibly some\r
+ desktop systems) come wired with an internal USB hub between the\r
+ ports and the system bus, which can then cause problems for various\r
+ kinds of external USB devices, including some models of audio\r
+ interfaces. It is very difficult to discover whether this is true or\r
+ not, without simplying trying it out.\r
