Public bug reported:

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.
