Thanks for all who could help me to install a driver for smart card reader Ricoh Co Ltd RL5c476 II (rev b9).

The driver is available here: Ricoh RL5C476

And according to http://sdricohcs.sourceforge.net/ the driver has been included in the official kernel sources.
Unfortunately the smart card reader Ricoh Co Ltd RL5c476 II still not recognized by Ubuntu for me.
Windows XP works with it correctly.

I did not manage with installing the driver because of missing: kernel-source and kernel-syms

Ricoh RL5c476 is a multifunction (4-in-1) device and the driver you linked supports the MMC/SD part of the chip. Unfortunately, you will have no chance of getting the SC reader part to work with Linux because, as far as I know, there are no public specifications available.

The most recent source I could track is rather clear:

Dear Martin,

Thank you very much for the proposal. However, we don't have the intention of disclosing our technical information for linux driver.

Best regards,

(http://www.mail-archive.com/muscle@lists.musclecard.com/msg07782.html)

However, the software overview of some HP notebooks (for instance, HP-Compaq 6910p) reports a generic Certified SuSe Linux Enterprise Desktop 10, meaning that there could be a non-free driver somewhere in the wild, but do not count on that.
