Apparently, at
least with the Cyberflex, the card responds with its maximum speed and
the Gemplus driver interprets this as the requested speed.
If so, that would be a bug in the reader driver. The card remains at
default timings until the reader sends it a PPS.
By the way, the Cyberflex card actually will run at higher speeds than the
atr would normally indicate. You can take advantage of the higher speeds by
sending the card a ChangeJavaATR with different timings.
