The IN transfer was 1 frame long and scheduled for frame 1123, so its

have completed in frame 1117. But the timestamps show that the two
URBs completed at the same time (only 13 us between them).
Furthermore, I clearly recall Sarah Sharp (the original maintainer for
xhci-hcd) saying that the support for isochronous transfers needed
attention. This may well be an example.

Hi,
Is there any progress on this or is it low priority?
I'll add checking the xhci side of this to my TODO list, (which starts
to be quite long already). Might take some before I get to it.
