Are you sure the phone is handling this properly? Many times it will refuse to connect to a host at all until you tell it is safe to do so somehow (like change the USB mode.) > I will gladely help troubleshooting the issue, having a usb port less over 3 is really problematic I don't understand this question, sorry. greg k-h
