Is i possible that the device needs an init sequence you don't do?

/*
 * The current device is removed, the USB layer tell us to shut it down...
 */
static void kingsun_disconnect(struct usb_interface *intf)
{
	struct kingsun_cb *kingsun = usb_get_intfdata(intf);

	if (!kingsun)
		return;

	unregister_netdev(kingsun->netdev);

Call usb_unlink_urb() on your urbs before you free their buffers.

	kfree(kingsun->out_buf);
	kfree(kingsun->in_buf);
	kfree(kingsun->prev_rx);
	free_netdev(kingsun->netdev);

	usb_set_intfdata(intf, NULL);
}

#ifdef CONFIG_PM
/* USB suspend, so power off the transmitter/receiver */
static int kingsun_suspend(struct usb_interface *intf, pm_message_t message)
{
	struct kingsun_cb *kingsun = usb_get_intfdata(intf);

Here kill the urbs

	netif_device_detach(kingsun->netdev);
	return 0;
}

/* Coming out of suspend, so reset hardware */
static int kingsun_resume(struct usb_interface *intf)
{
	struct kingsun_cb *kingsun = usb_get_intfdata(intf);

Restart the urbs.
