[sane-devel] Plustek OpticFilm 8200i

[Brian Clinkenbeard]

Hi,

I've recently picked up a Plustek OpticFilm 8200i and I'm interested in helping to add support for this device to SANE. According to [this site](https://www.filmscanner.info/en/PlustekOpticFilm8200i.html), the 8200i is identical to the 7600i other than the SilverFast software that is bundled with the scanner. Using sane-find-scanner tells me the device uses a Genesys GL845 but it's more likely according to older threads about the 7600i that it uses the GL843 chipset. I've attempted to disassemble the device but the chipset appears to be hidden within a crevice against the back plate so I was unable to confirm this.

Here are the relevant command outputs:
