It would be the perfect solution.
But the value of SCARD_CTL_CODE(3400) is not documented anywhere. So I
had to chose one. Yes, I could have written a Windows program to get
the value under Windows. But I do not use Windows.

I think it is the job of rdesktop and other RDP clients to convert the
values between the 2 worlds.
I just added support of the windows value 0x313520 in the CCID driver
revision 6739.

But the problem should be elsewhere since the same application worked
with pcsc-lite 1.6.4.
