It appears that the epkowa backend has the product ID wrong.
Stylus CX5100/CX5200 0x0801
Stylus CX5300/CX5400 0x0808
On a related note, the CX6600 is listed with two product IDS, but it

the other models do not have a corresponding Japanese version.
We'll put fixing this on the list the next iscan release.

There is also a Debian bug that mentions it:
The right thing to do is to remove the block from the code of the
