It looks like this patch:
accf227de4d2 ("USB: serial: option: Add support for Quectel RM500Q"),
so I copied that patch and replaced VID/PID with FG150, rebuild kernel,
and it works well.
PS:
In Fibocom's Windows driver, they hardcoded USB interface, which
looks like:
> I: If#=0x0 --> Remote NDIS Compatible Device
> I: If#=0x1
> I: If#=0x2 --> Fibocom USB Modem // Modem
> I: If#=0x3 --> Fibocom USB Diagnostics (COMx)
> I: If#=0x4 --> Fibocom Modem_SN:XXXXXXXX //WinUSB, ADB
