static int hub_suspend(struct usb_interface *intf, pm_message_t msg)
{
struct usb_hub *hub = usb_get_intfdata (intf);
struct usb_device *hdev = hub->hdev;
unsigned port1;
/* fail if children aren't already suspended */
for (port1 = 1; port1 <= hdev->maxchild; port1++) {
struct usb_device *udev;
udev = hdev->children [port1-1];
if (udev && udev->can_submit) {
if (!hdev->auto_pm)
dev_dbg(&intf->dev, "port %d nyet suspended\n",
port1);
return -EBUSY;
}
}
You will get into the code path that returns -EBUSY and the suspend will
fail.
