Thank you for your report.

For the development, I can't just apply your patch, because it breaks
my environment.

The PPS setting is basically for my own card reader of Gemalto PC.
Another software like libccid does same thing for Gemalto PC.

I will add some code to identify a reader and only sends PPS for Gemalto
