I have mx53 based hw running Linux ( and usb otg port is configured to be used as a host. There is just one problem. It doesn't recognize when the usb device is plugged in. If I remove driver modules, plug the usb device in and load the driver modules the usb device is found and works ok. But if the driver modules are already loaded and I plug the usb device is, Linux doesn't see that usb device has been plugged in.


Is there something that should be done for the otg port or is this otg port feature or any clue what might be wrong?
