The HP lt4132 is a rebranded Huawei ME906s-158 LTE modem.
The interface with protocol 0x16 is "CDC ECM & NCM" according to the *.inf files included with the Windows driver. Attaching the option driver to it doesn't result in a /dev/ttyUSB* device being created, so I've excluded it. Note that it is also excluded for corresponding Huawei-branded devices, cf. commit d544db293a44a.
