A fix like this is already in CVS and will be included in the
next release of sane-backends :)
Except in the CVS version, this scanner is treated as a HP3400
instead of a HP4300.
The HP3400 and HP4300 are basically the same anyway;
the HP4300 has some extra buttons and a display
(which we don't use yet).

FYI, Silitek is the manufacturer of the 'niash' scanner control
chips.
