    Article from the serie "CCID descriptor statistics"

    The bAlternateSetting field is a number value from the USB descriptor: Value used to select this alternate setting for the interface identified in the prior field.

    All the CCID readers I have in my list have the same value: 0.

    bAlternateSetting # %
    0 254 100.00 %
