Hi,
Reproducer:
# ./qemu-qmp -drive file=disks/test.img,if=virtio,cache=none,aio=native \
-enable-kvm -m 1G -monitor stdio -usb -usbdevice host:1.43
QEMU 1.5.50 monitor - type 'help' for more information
(qemu) qemu-qmp: /home/lcapitulino/work/src/upstream/qmp-unstable/exec.c:1927: memory_access_size: Assertion `l >= access_size_min' failed.
I have an USB stick on 1.43, although I did manage to get this without
USB at all (forgot how, though).
Bisect says the bug was introduced by:
commit 23326164ae6fe8d94b7eff123e03f97ca6978d33

It's possible to reproduce it passing just -usb (I guess I was wrong about
reproducing it w/o USB).

Yes, we've already discussed it and agreed upon a solution.
I guess it hasn't been applied yet?
