thats the device and i try some houres around this rule:

SUBSYSTEMS="usb", KERNEL="sd??", ATTRS{serial}="SAMSUNG HDS0MUJ1NQA49906      ", SYMLINK+="usbplatte%n"

what is the trick? after every change on this rule i used 'udevcontrol reload_rules' but /dev dosen't show the device 'usbplatte'?

please give me a hint.
thanks a lot!
