Yep, you nailed it!

I've applied 
https://www.kraxel.org/cgit/qemu/commit/?h=work/usb-uhci-usb-host-debug&id=c69e5efac15db4340b880c80f27ebe536acd1aeb 
to my local copy of current qemu git master and the problem no longer 
exists.

The stderr debugging output is also beautifully silent :)

Awesome work, many thanks.
