[sane-devel] Canon CanoScan LiDE 90

[david.vlaminck at telenet.be]

Hi, 

I have a scanner that's not supported. This is a Canon CanoScan LiDE 90. 
I read on the sane website that the output of sane-find-scanner -v -v could be helpful. 
Can someone help me get this scanner to work? since the 80 and 100 model are supported it could be easy to get this to work? 

I edited genesys.conf by adding the following: 
# Canon LiDE 90 
usb 0x04a9 0x1900 

I don't know if that was good or bad but so far sane is not working. 

This is my output:
