Do you have any idea how I can localize the problem to find out at
what stage it fails? You know, same 200 lines of code work with one
kernel (3.4), but fail with another (mainline). Fist I thought it
might be a bug in my USB bus glue driver, but it doesn't look like
this. I've run out of ideas how to troubleshoot this issue.

Yes, I had this problem too and found that one liner already. I can
confirm - it works. But yes, USB problem is different one.
