usb-bot: hotplug support
This patch marks usb-bot as hot-pluggable device, makes attached property settable and turns off auto-attach in case the device was hotplugged. Hot-plugging a usb-bot device with one or more scsi devices can be done this way now: (1) device-add usb-bot,id=foo (2) device-add scsi-{hd,cd},bus=foo.0,lun=0 (2b) optionally add more devices (luns 0 ... 15). (3) qom-set foo.attached = true Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Reviewed-by: Markus Armbruster <armbru@redhat.com> Message-id: 1465984019-28963-5-git-send-email-kraxel@redhat.com
