As usual with Omnikey stuff: Docs are hard to get and they are not eager
to help developers to get their hadware working.

I had severe problems with mine; according to people working with the
Windows driver it is known that these readers have problems with
extended length APDUs.  I have not used mine for weeks; I'll try it

The driving force is that we have the new OpenPGP cards and can't use
them with laptops.  The CM4040 pccard reader is widely used and I
suggested it in the past to many folks; they are now using it on a daily
base (including me).

I know ;-)
