Yes, that should be correct.

The file is most probably ok.

You're right - the 5300 entry is the one for the 5300U. The problem 
you're reporting has been experienced before by other people (hence 
my remark on that scanner on the snapscan page). I don't know yet how 
to solve this problem - maybe the log from the USB layer can shed 
some more light. To produce it, use SANE_DEBUG_SANEI_USB=255.
