yes, thought so too, but it's working without. I can confirm that the 
flash drive works fine and is automatically detected with the (trivial) 
patch given in the other mail. The patch is against 4.6, but it applies 
cleanly against the current linux-next and axboe/linux-block.

In my boot scripts, I had to include a short sleep because I was too 
lazy to properly wait for the device files to come into existence.

Thank you for your answer!

LLAP,
