I recently tried using the new PC/SC CardTerminal software in an
existing app that uses PC/SC and OCF.

I find that it breaks my app:

It is a file system app and, after I select the app on the card I then
attempt to select the first DF on the card using the command: 80 A4 00
00 02 10 00

Using the old PCSC CardTerminal this works fine and I get back the
response 61XX (where XX is the size of the response data) and a
subsequent 00 c0 00 00 XX command gets me the full response data.

If I switch to using the new PC/SC wrapper the select DF command results
in a 6d 00 (instruction not supported).  I have tried the same command
with an extra 00 at the end for Le but it makes no difference.

Is this some side effect of the fix for the T=0 long APDU bug in the
original wrapper or something else?
Do I have to change something in my configuration or code to get this to
work using the new wrapper?

cheers
Brian
