Scanner or Photoshop issue?

I've been using a Canon Canoscan 9000F Mark II to scan slides and negatives into a MacBook Pro and all was fine until upgrading the Mac to Yosemite.  Now, my scans won't open in Photoshop CS6 and I get the following error message:

``Could not complete your request because a SOFn, DQT, or DHT JPEG marker is missing before a JPEG SOS marker.''

Is the fix a driver from Canon or a Photoshop issue?
