bcdDevice 7.04 signals a genesys chip newer than the
GL124 (which has7.01). Since GL128 is 7.05, we could bet on
a GL126 (there is also a GL125), or like the GL8417 and
GL124, another one specially taylored for Canon, a GL127? .
Anyway, I don't know any public datasheet for these ASICs,
which complicates the work for supporting it. One would have
to guess what registers are used for. <br>

Hi. <br>
<br>
Thanks for the reply. <br>
<br>
Should I give up and return this scanner, or is there a way I
can help build a driver for it? (if its not too complex!). <br>

Hello,<br>
<br>
the C code in the genesys backend isn't that complicated. What
takes time is the guess work on the ASIC behavior and tests
involved. The guess work will even be bigger without a datasheet.
Have a look at the rts8891 backend sources to have an idea of this
work.<br>

Stef<br>
