I have an old Canon CanoScan FS4000US Slide Scanner. I have connected it via USB to an Intel iMac running Mac OS 10.7.5, and in System Report, I can see that it is connected. Also, when I disconnect and reconnect the USB cable, the slide tray ejects on the scanner. What I would like to know is if there is any way to mount the scanner properly as a device so that it will be available in Image Capture. I downloaded VueScan, a third-party software, that is able to see the device and process a scan, so there must be some way to get the drivers to see the device in Image Capture. Any ideas?
Have you tried installing this comprehensive Apple Canon Printer/Scanner driver set? I dont have an FS400US I can test this with but its worth a shot.
