I do have hardware for that around, so once you've respun your patch to
address the issues discussed, then that will give me a nice basis to
add usb-3 usb-stick to ehci-controller redirection :)

Hmm, there is (was) one know issues with these devices, which has been fixed
in usbredir, so first of all make sure that the usbredir on your spice-client
/ usbredirserver, has this patch:
http://cgit.freedesktop.org/spice/usbredir/commit/?id=7783d3db61083bbf7f61b1ea8608c666b4c6a1dd

If that does not work, add the debug parameter to the usb-redir device, set it
to 4, collect logs of trying to redirect the device and send me the logs
please, ie:
-device usb-redir,chardev=usbredirchardev1,id=usbredirdev1,debug=4

Also be aware that usb-redir relies on chardev flowcontrol working,
which it does not upstream! See for example here for the chardev flow
control patch set which RHEL / Fedora carry:
http://cgit.freedesktop.org/~jwrdegoede/qemu/log/?h=qemu-kvm-1.2-usbredir&ofs=50

And then the first 13 patches after: "Merge tag 'v1.2.0'"

Oh, and also, if you're running qemu git master, make sure you've:
http://cgit.freedesktop.org/~jwrdegoede/qemu/commit/?id=81e34f5973d8d6a1ef998a50c4a4bf66abb3b56b
