Bug description:
  Hello.

  qemu / kvm does not start anymore after upgrading ubuntu from 19.04 to
  19.10 and qemu from 3 to 4,as you can see below. what can I do ?

  root@ziomario-Z390-AORUS-PRO:/home/ziomario/Scrivania/OS-KVM# ./boot-
  OS-HSP2.sh

  ----> qemu-system-x86_64: /build/qemu-
  UryNDZ/qemu-4.0+dfsg/hw/usb/core.c:720: usb_ep_get: asserzione "dev !=
  NULL" non riuscita.

  It seems that this line is not good anymore (it worked with qemu 3.x)
  :

  -usb -device usb-host,hostbus=1,hostaddr=7 \

  when I removed it,it works. But I need that. With what can I change it
  ? You can reproduce that upgrading ubuntu 19.04 to 19.10 because in
  that way also qemu will be upgraded from 3 to 4. These are the
  packages that I'm using :

  root@ziomario-Z390-AORUS-PRO:/home/ziomario# qemu-system-x86_64 --version
  QEMU emulator version 4.0.0 (Debian 1:4.0+dfsg-0ubuntu9)
