Message:

Support CCID 1.10 and fix pts and parameter setting in the proper order

By: Chaskiel Grundman

I have apparently been sitting on a patch that does pts and parameter setting in the proper order for most of a year. (the problem you have seems to be that the existing code changes the baud rate before doing pts, so the card responds at the old baud rate) I do not know why I did not submit this patch earlier. I do know that I have not really tested it recently
