My problem is that immediately upon connecting the usb cable the phone is choosen as a modem. When I select the USB Mass Storage option the phone displays a picture of a phone and a pc with a dot bouncing back and forth between them but there is no indication on the Debian terminal of any change. Leaving the phone in this mode I disconnect and reconnect the usb cable. The result shown in syslog is

Neither of these can be mounted. I think there must be a way to tell udev or the kernel to let go of the device ttyACM0 and recognize a usb connection to a mass storage device.
