first of all thanks for being so cooperative on this issue.

To recap: As far as we know, the current images on master branch have a
bug with some boards, which is due to the SDK version we compiled with.
On these boards, streaming will fail pretty soon at high rates (a few
minutes if streaming at max rate).
This is a known issue, and as mentioned, we'll have a fix very soon.

On maint branch on the other hand, we are not certain there's a bug, as
reports have been inconclusive, and we were not able to reproduce this
in our lab. We know for a fact that there are *many* buggy USB3 chipsets
out there (your's is, as far as we know, not one of them).
Maybe VM's exacerbate this issue as well.
So, any version of the 3.7 release series should work.

When you say your maint branch has a problem, but not quite so bad, I'd
like to know what exactly this means, so we can get down to this problem.
