Title:
  Cannot use usb-host on Mac OS

Status in QEMU:
  Expired

Bug description:
  Usb-host will not work on Mac OS 10.15.  Qemu runs, though it gives
  these errors and the drive does not show up.  Also, when Qemu is
  starting the drive ejects and remounts twice. Qemu built with
  ./configure --target-list=i386-softmmu,x86_64-softmmu --enable-sdl
  --disable-cocoa --enable-sdl-image.
