Cannot use usb-host on Mac OS

[John Canada]

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.

Yes, I tried running as root. I also tried it on a different computer that is running Mac OS 10.13, and it gave the same errors.

I am also having problems with using real USB devices. I tried a C-Media USB sound card, a CISCO USB headset, and a PNY flash drive. All of them seem to be detected by the Windows 7 guest, but can't be started for some reason. I have tried running as root. I didn't see any libusb errors. My Windows 2000 guest also has issues with starting the USB sound card.

My command-line:
sudo qemu-system-x86_64 -hda "Windows 7 HD.qcow2" -boot "c" -m 5000 -device ich9-usb-ehci1 -device usb-host,vendorid=0x0930,productid=0x6545

Even when I unmount the flash drive first Mac OS 11.1 will actually mount the flash drive when I try using it in QEMU.
