Photoshop CS4 is not picking up my Scanner?

I had cs3 and it worked fine recently updated to cs4 and now I've tried to scan and its not appearing in the import options. Its the Cannon Mp210 model.

Is there something I need to do under preferences in order to get it to up date? or to make it appear?

Thanks in advance.

You need to install the canon plug-in, it will be in CS3's plug-ins folder if that is still on the machine

Otherwise download the latest Canon package

Canon PIXMA MP210 Photo All In One Printer

I downloaded the latest driver and installed it but nothing changed. I downloaded the top one. Did I download the wrong thing?

its the one called

MP210 series Scanner Driver Ver. 13.9.0 (Mac OS X)

I downloaded it, installed it and its still not picking it up?
