A recent patch (9d9a04ee) added support for the new machine, but got
the sequence of USB ids wrong. Reports from both Ian and Linus T show

number 0x0290. This patchs moves the three numbers accordingly, fixing
the problem.

0xfb to 0xfa t

That's fine by me, I just want the patches in ASoC - obviously the
