Hotplugging them simply doesn't work, so tag them accordingly to avoid users trying and then crashing qemu. For xhci there is nothing fundamental which prevents hotplug from working, we'll "only" need a exit() function which cleans up everything properly. That isn't for 1.3 though. For ehci+uhci+ohci hotplug can't be supported until qemu gains the capability to hotplug multifunction pci devices. https://bugzilla.redhat.com/show_bug.cgi?id=879096 Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> --- hw/usb/hcd-ehci-pci.c | 1 + hw/usb/hcd-ohci.c | 1 + hw/usb/hcd-uhci.c | 1 + hw/usb/hcd-xhci.c | 1 + 4 files changed, 4 insertions(+), 0 deletions(-)
