I have a device with the same Vendor Id and Product Id as Eddotans. Mine is too a generic mp3 player, but different brand. Now I've finally got it to appear as a USB mass storage device. I've done some other fiddling before so I don't know if this alone did it, but this is what I have to do in order to mount it:

modprobe -r usbtouchscreen
modprobe -r usb_storage
modprobe usb_storage

This is sort of a hack of course. If anyone else has a more permanent way of doing it it would be welcome.
