Confirming the fix by Michael B also works with a Samsung S5510.

The problem is with usb_mode_switch and the associated udev rules in /lib/udev.d/rules/40-usb_modeswitch.rules:

# Samsung U209
#ATTRS{idVendor}=="04e8", ATTRS{idProduct}=="f000", RUN+="usb_modeswitch '%b/%k'"

These lines do not represent a unique product; the Samsung Xcover 271 B2710 and Samsung S5510 (and others??) also match this line (lsusb gives 04e8:f000).

Commenting out this line fixes the problem on the Samsung 5S5510, and I would guess the Xcover 271 B2710 too.
