Hi to all,

my Name is Stefan Kögl, and I'm working with the system security group
at Ruhr-Univerity Bochum, Germany. We are conducting together with industry
partners a large user study on secure IT infrastructures, which includes the
usage of smartcards.

For this research project we would appreciate your expertise with
a GPL Linux driver for a Ricoh PCMCIA smartcard reader
PCMCIA_DEVICE_PROD_ID12("RICOH", "Bay8Controller", 0xd9f522ed, 0xb8dd2c87)
written by SCM and which is unreleased yet. We have tried to use the driver
and extending the code to complete support for different protocols. However,
we ran into problems, for which we hope you can help us.

Technical details:
We had to add T=1 support, but we only got the driver without any
technical documentation. We ported the module to the actual linux
kernel api and included the  mandatory T=1 protocol, but we got
communication issues between IFD and ICC and eventually we don't know
how to fix it.

Can someone help us or point us to the right person who can handle this?

Sincerely yours,
Stefan Kögl
