Thank you, I will look forward to it.

are you means there some old pcsc driver will eject a out buffer with 258
bytes? as my experience, many pcsc driver will handle this correctly.

the card is developed by me, i'm not sure whether i can send it to you. the
fault was caused by the out buffer is too samll for store the response data
and the status word, in my case the apdu send to card is: 00 C0 00 00 00,it
requires 258 (256+2) bytes to store the outter data, however the buffer
provided by the program is 256 byte, the pcsc back end will failed to handle
this apdu.

my card reader is Gemplus USB: Gempc-usb-sw, the reader backend is pcsc, i
using other pcsc software with this reader, it can support the function
correct, this feature is very important to me, because my card can support
long RSA key, such as 2048 bits, and GunGP cann't work with suck card.

sorry, it was in the line 2710
