in the authors list view on my Kobo. It is a Libra2

Do I miss something somewhere ?

For plugboards, the Libra2 is a "KoboTouch" device, not a "Kobo".

Looking at the driver code, the "Kobo" devices are:

    ORIGINAL_PRODUCT_ID = [0x4165]
    WIFI_PRODUCT_ID     = [0x4161, 0x4162]

The KoboTouch devices are:

    AURA_PRODUCT_ID     = [0x4203]
    AURA_EDITION2_PRODUCT_ID    = [0x4226]
    AURA_HD_PRODUCT_ID  = [0x4193]
    AURA_H2O_PRODUCT_ID = [0x4213]
    AURA_H2O_EDITION2_PRODUCT_ID = [0x4227]
    AURA_ONE_PRODUCT_ID = [0x4225]
    CLARA_HD_PRODUCT_ID = [0x4228]
    CLARA_2E_PRODUCT_ID = [0x4235]
    ELIPSA_PRODUCT_ID   = [0x4233]
    ELIPSA_2E_PRODUCT_ID   = [0x4236]
    FORMA_PRODUCT_ID    = [0x4229]
    GLO_PRODUCT_ID      = [0x4173]
    GLO_HD_PRODUCT_ID   = [0x4223]
    LIBRA_H2O_PRODUCT_ID = [0x4232]
    LIBRA2_PRODUCT_ID   = [0x4234]
    MINI_PRODUCT_ID     = [0x4183]
    NIA_PRODUCT_ID      = [0x4230]
    SAGE_PRODUCT_ID     = [0x4231]
    TOUCH_PRODUCT_ID    = [0x4163]
    TOUCH2_PRODUCT_ID   = [0x4224]

If you run calibre in debug mode then you can see what the plugboard does when you connect/send to the reader.
