Hi,
There is no problem to loop over all usb devices. But first of all I
don't want to loop on used, since then I miss any detached devices,
so I actually do want the same behavior of qdev_find_recursive, and
since it's already available, why rewrite it in a different
compilation unit?
Point
+USBDevice *usb_device_by_id(const char* id)
+{
+USBBus *bus;
+DeviceState *qdev;
+USBDevice *dev;
+
+QTAILQ_FOREACH(bus,&busses, next) {
+qdev = qdev_find_recursive(&bus->qbus, id);
+if (qdev != NULL) {
+dev = DO_UPCAST(USBDevice, qdev, qdev);
