I'm willing to help hack a solution for this, since this new model
of the canon lide series is bound to become popular over the next
weeks / months (its not a niche model). <br>

Hello,<br>
<br>
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>
<br>
Regards,<br>
Stef<br>
