Actually, looking at the QEMU source code, I am not able to spot the USB hcd emulation code that backs a PCI MMIO BAR using host memory, and in fact, the only instance I *can* find is vga-pci.c @Alex: could you please explain which exact issue with USB emulation is suspected to be caused by this? @team-RH: are there any other examples beyond VGA PCI where this is a problem?
