this won't work, because the additional protocol descriptor list is a
sequence of sequence of sequence. Compare this from my HCRP capable
printer:

Attribute 0x0004 - ProtocolDescriptorList
        Sequence
                Sequence
                        UUID16 0x0100 - L2CAP
                        UINT16 0x1003
                Sequence
                       UUID16 0x0012 - HardcopyControlChannel

Attribute 0x000d - AdditionalProtocolDescriptorLists
        Sequence
                Sequence
                        Sequence
                                UUID16 0x0100 - L2CAP
                                UINT16 0x1001
                        Sequence
                                UUID16 0x0014 - HardcopyDataChannel
