Why this test?
In my list the KAP-LINK2 has 3 CCID interfaces https://ccid.apdu.fr/ccid/shouldwork.html#0x29470x0105

Do you have another model with a different configuration but using the same idProduct?

This test is needed as KAP-LINK2 is a USB composite device presenting either 3 CCID interfaces or 3 CCID interfaces (the 3 first ones) and a CDC-ACM interface according user configuration

I see.
It should work fine if you something like use:

max_interface_number = 3; /* up to 4 interfaces */
num_CCID_interfaces = 3;  /* 3 CCID interfaces */

@bmoraine Is it possible for the KAP-LINK2 to NOT have 3 CCID interfaces?

Why can't we use max_interface_number = 2; in all cases without checking the value of config_desc->bNumInterfaces?

@LudovicRousseau Effectively, KAP-LINK2 has always 3 CCID interfaces (the 3 first ones) and an optional 4th CDC-ACM interface. So, you are right, we can use max_interface_number = 2; in all cases without checking the value of config_desc->bNumInterfaces

{
max_interface_number=2;
DEBUG_INFO1("Kapelse reader restricted as multislot with 3 slots!");
}
else
{
max_interface_number=config_desc->bNumInterfaces-1;
DEBUG_INFO2("Kapelse reader forced as multislot with %d slots!",max_interface_number+1);
}
break;

default :
/* Kapelse : all interfaces are ccid ones */
max_interface_number=config_desc->bNumInterfaces-1;
DEBUG_INFO2("Kapelse reader forced as multislot with %d slots!",max_interface_number+1);
break;
}
}
#endif

usb_interface = get_ccid_usb_interface(config_desc, &num);
if (usb_interface == NULL)
