Hardware, Embedded Systems Intel and others plan to release a new version of the ubiquitous Universal Serial Bus technology in the first half of 2008, a revamp the chip maker said will make data transfer rates more than 10 times as fast by adding fiber-optic links alongside the traditional copper wires. Intel is working with fellow USB 3.0 Promoters Group members Microsoft, Hewlett-Packard, Texas Instruments, NEC and NXP Semiconductors to release the USB 3.0 specification in the first half of 2008, said Pat Gelsinger, general manager of Intel's Digital Enterprise Group, in a speech here at the Intel Developer Forum.

Perhaps it is because it replaced the old Serial ports, which provided a very basic interface that nearly any device could communicate over and create its own protocol over.

So, this is likely on purpose and done specifically to allow the same amount of freedom in the protocol that the old serial devices had. Thus why you would have to have an extensive software interface that monitors even the lowest level errors - it's really a driver interface to some unknown device that only the driver knows how to completely communicate with and interpret, which btw has to run on the CPU.
