static int hub_port_suspend:

	if (udev->do_remote_wakeup) {
		status = usb_control_msg(udev, usb_sndctrlpipe(udev, 0),
				USB_REQ_SET_FEATURE, USB_RECIP_DEVICE,
				USB_DEVICE_REMOTE_WAKEUP, 0,
				NULL, 0,
				USB_CTRL_SET_TIMEOUT);
		if (status)
			dev_dbg(&udev->dev,
				"won't remote wakeup, status %d\n",
				status);
	}

Having the capability is not enough. Per default it is switched off.
Devices without drivers can't do remote wakeup. Which driver is this device
bound to?
