The devices file looks correct.  This is a difficult problem...

Is the usb-storage driver loaded when you plug in the drive?

Is CONFIG_USB_LIBUSUAL enabled in your kernel config?

Can you build your own kernel for testing?  If you can, enable 
CONFIG_USB_DEBUG and let's see what shows up in the dmesg log.

CONFIG USB LIBUSUAL is not set, neither is USB DEBUG. I might be able to compile
my own kernel within a few days, no internet access right now.

usb storage module gets loaded when i plug the device, but i also tried to
modprobe it before i plug it in.

Thanks for your efforts.
