Can you test what happens with piix4 + usb2? (I suspect you can't as
osx will simply not boot then due to the piix4 being much older than the
intel port of osx).
I think ovmf simply doesn't get the IRQ routing right (doesn't
initialize PCI_INTERRUPT_LINE register correctly). It is *not* the same
on piix and q35. See piix_pci_slot_get_irq vs. mch_pci_slot_get_irq in
seabios source code.
I think if you boot linux guests with "noacpi" it will have trouble with
usb interrupts too.
cheers,
Gerd
