Here is the error.  I guess that pinmax=25 is the issue (as same as
cyberJack go).

In the function pcsc_pinpad_verify (gnupg/scd/apdu.c), we have:

    pininfo->maxlen = 25;

The value is copied from ccid-driver.c, and this value seemed to come
from SPR532.  I think that SPR532 is rather special, and it is better
to have default value of 15, and let SPR532 to change the value.

I will change the code (apdu.c for PC/SC, and ccid-driver.c) to do
that.
