Hi Brian,

I have already connected up to 15 readers in the same time on the same PC using USB 
hubs and they work fine with PC/SC Lite.
You may connect up to 255 readers but you must modify a define in the source code of 
PC/SC Lite.
In pcsclite.h change #define PCSCLITE_MAX_READERS_CONTEXTS  16 to #define 
PCSCLITE_MAX_READERS_CONTEXTS  256 and recompile all.

I developed the IFDHandler for the GIS SM1's (serial) [1] but actually it supports 
only 1 reader at the same time.
I should improve it after the middle of february. As I had not feedback, I have not 
worked more on this IFDHandler.
If you want to connect more than 2 SM1 it seems to me that there is serial hubs but a 
solution based on USB seems better.
