So I've been looking through the code and the specs and couldn't really 
find anything that differs between the LS50ED specs and the current 
coolscan2 code. Here's a trivial patch to enable the detection of the 
LS50 and LS5000, maybe this is all that is required to get these devices 
to work for a start. You may need to adjust usb IDs too, not sure.
