I don't have an S300 or S1300 here but I'm wondering if they have
different hardware or they are exactly the same? What about the firmware,
if those devices were the same, was it possible to load the S300 firmware
on all the devices somehow so they behave the same?

That's sad :(
What about the code to generate devices names based on serial? Do you have
a separate patch (or is it already a big change)? That's one of the things
I like with the fujitsu backend and I'd like to have the same here.
