[Bug 1851547] Re: qemu 4 crashes with this parameter attached -usb -device usb-host, hostbus=1, hostaddr=7 \

[Thomas Huth]

The QEMU project is currently considering to move its bug tracking to
another system. For this we need to know which bugs are still valid
and which could be closed already. Thus we are setting older bugs to
"Incomplete" now.

If you still think this bug report here is valid, then please switch
the state back to "New" within the next 60 days, otherwise this report
will be marked as "Expired". Or please mark it as "Fix Released" if
the problem has been solved with a newer version of QEMU already.

Thank you and sorry for the inconvenience.

  qemu 4 crashes with this parameter attached -usb -device usb-
  host,hostbus=1,hostaddr=7 \

Status in QEMU:
  Incomplete

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-

  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)
