The bInterfaceNumber field is a number value from the USB descriptor: Number of this interface. Zero-based value identifying the index in the array of concurrent interfaces supported by this configuration.
| bInterfaceNumber | # | % |
|---|---|---|
| 0 | 207 | 81.50 % |
| 1 | 36 | 14.17 % |
| 2 | 10 | 3.94 % |
| 4 | 1 | 0.39 % |
Many CCID readers only have 1 interface. So the CCID interface is numbered 0.
Readers with 2 or more interfaces are composite devices. They can be either a reader with 2 CCID interfaces or a device with a CCID interface and other interfaces like a mass storage.
Readers with 2 (or more) CCID interfaces are listed in more than one list. For example the "Gemalto Prox Dual USB PC LinkReader" is listed in bInterfaceNumber = 1 and also in bInterfaceNumber = 2 because one CCID interface has bInterfaceNumber = 1 and the other has bInterfaceNumber = 2. And in this the interface number 0 is HID.
The "Gemalto IDBridge K3000" is listed only in the list bInterfaceNumber = 2 because the interfaces 0 and 1 are HID and mass storage.
