You can have a look at
http://www.gemplus.com/techno/tlp_drivers/index.html for a library that
would allow you to communicate with this kind of reader. However:
- this is not a PCSC-lite driver;
- it uses the TLP protocol which is not optimal for this kind of reader.

It should be easy to write a driver based on the ifdGemPC for the 410
(it uses the GBP or Gemplus Block Protocol).

There is a set of APDU commands to read the records on the card. I think
you should read http://www.gemplus.com/dwnld/291_E5255001.pdf (reference
manual of the GCR680 which should be compatible).

You could maybe use the "get first card" command (see reference manual)
to detect card presence. Supporting more than one card at a time would
be tricky...
