Supplement:
This situation a bit different. Here all ISO packets failed with -EXDEV
within that URB. I treat this this like no Error by resubmitting the
URB, but this leads to a complete -EXDEV again and again. When finally a
submit_urb() failed with -EFBIG, the endpoints is no longer served by
the driver.

At all of my previous reports I got the -EXDEV only partially in 3 of 8
packets within a single URB and no problem with resubmitting...

Thanks a lot, Martin
