Today, While casually surfing various support forums of Ubuntu and Mandriva, I stumbled upon this How To guide to get the Ricoh Card Reader (Internal) working on Ubuntu for various laptops.
For your information, I am running Ubuntu 8.04 – Hardy Heron. I tried the guide — though what was said made little sense to me — and got my card reader working.
So, give your luck a shot if you have been disappointed with the card reader not working on your laptop 🙂
