When I disconnect HID Omnikey reader, in syslog appears:
pcscd: ccid_usb.c:660:WriteUSB() write failed (1/8): -4 No such device

That means CCID is in fact used, so I will have to modify libccid
package also, right?

We're going to use Debian (instead of two Windows machines, yay! :-)
), so I am planing to create local repo for modified packages I guess.

Oh, so Idea is to use update codebase to use list instead? I wish I
could help, but I kinda doubt I could provide quality C when having
experienced mainly with C++ only.

Sorry for not being clear, as English is not my native language... I
wanted to ask if anyone knows USB device that could be bought that has
lot's of smart card slots bundled in it.

Thanks for reply, Ludovic
