uscanner is unnecessary.  You can use the ugen0 device.

Add the USB IDs to /usr/local/etc/sane.d/genesys.conf:

    # CanoScan LiDE 90 (untested)
    usb 0x04a9 0x1900

Haven't tried 64-bit, and the sane-genesys man page has warnings about 
pulling the plug on the scanner if the scanning head hits the stops. 
If you were using 32-bit, there's a slim chance of getting the Windows 
scanning software to work under Wine.
