Subject: [PATCH v2] USB: serial: option: add Fibocom L7xx modules
Date: Tue, 21 Nov 2023 21:05:56 +0000	[thread overview]
Message-ID: <39dd187fe27244f28fa729ce134d9d130147f2e1.camel@hotmail.com> (raw)

Add support for Fibocom L716-EU module series.

L716-EU is a Fibocom module based on ZTE's V3E/V3T chipset.

Device creates multiple interfaces when connected to PC as follows:
 - Network Interface: ECM or RNDIS (set by FW or AT Command)
 - ttyUSB0: AT port
 - ttyUSB1: Modem port
 - ttyUSB2: AT2 port
 - ttyUSB3: Trace port for log information
 - ADB: ADB port for debugging. ("Driver=usbfs" when ADB server enabled)

Here are the outputs of lsusb and usb-devices:
$ ls /dev/ttyUSB*
/dev/ttyUSB0  /dev/ttyUSB1  /dev/ttyUSB2  /dev/ttyUSB3
