I have downloaded and decoded the log. I can confirm it is a
genesys based device. However since the chip used can only do 2400 dpi
max, I expect some hardware trick if this scanner can reach the 7200
Another thing is that used SCANMOD is tagged 'RESERVED' in GL842
datasheet. So I expect it will be different from other supported
scanners that don't use this SCANMOD
So since it is no close enough to other devices I have, I cannot
add support for this model without having the real hardware.
