00000002 prothandler.c:124:PHSetProtocol() PTS failed (612), using T=1

The reader fails to negociate the IFSD (Information Field Size for CCID for
protocol T = 1)

The value returned by the reader "92 82 00 10" is very strange (bogus?).
The CCID driver tries 3 times the same command and then gives up.

As Francois Grieu wrote in another email (thanks for that) this card can
use a very fast communication.
Your reader [1] defines:
dwDefaultClock: 4.800 MHz [3]
and
dwMaxDataRate: 826000 bps [4]

So the card could communicate at 300 kbits/s.

Your card is not yet in my list. Could you add it using [2]? Or tell us
what this smart card is?


Francois proposed different solutions to solve the problem.
There is no easy way to force a TA1 in the driver. Maybe the simplest fix
would be to change the value of dwMaxDataRate for this reader and use a
(much) lower value instead.

Proposed patch:

12903 is a very low value. This is the lowest/default data rate of the
reader (dwDataRate [5])
You can increase it up to 826000 and see when the reader fails.
