Is a good start. It has links to other resources as well. This has started
to be an issue in linux starting with kernel 3.13 or so (at least that is
where I see the bug reports lp: #1308628, It could be earlier as the
reporter was using 3.2 before upgrade) when the USB3 driver xchi-hda
shows up. (that seems to indicate to me that earlier kernels do not
support USB3) Mother board manufactures may choose to use other HW for
their USB3 ports even with the ivy bridge chip. This would not affect
USB1.1 audio stuff and may not affect all USB2 audio gear either. It has
affected both native instruments and presonus interfaces though. In the
windows world, it seems there have been driver changes to fix this.

In all I know less than I would like. I do not have any USB2 audio gear,
or any USB3 ports. My take on the Intel possition is that once the chip is
out it can't really be fixed so call it "not a problem". Fix it in the
next version. A recall on chips that are soldered to the board is even
harder than just the pluggable cpu and it affects a very small percentage
of users. Even in the audio community USB2 audio device users with no
option but usb3 ports is small.
