Hi Lars, sorry about the wrong order, I will correct it.
But about the ZTE device ID, I belive that we should insert among
Fibocom drivers because we are talking about a Fibocom module that is
using an ZTE Chipset.
So, this is exactly the same situation from Fibocom L610 IDs (0x1782,
0x4d10 / 0x1782, 0x4d11) that is using the Unisoc Chipset but were
inserted among Fibocom drivers.
And about the usb-devices output, let me explain better:
I am a Field Application Enginner at Fibocom Brazil and I am using the
IDs from our internal and official documentation.
On this documents its suggested to add all this IDs because it will
guarantee that can be used on all the variants devices from L71x series
(that can change according to different part number, region support or
network protocol).
Unfortunately, I don't have all the modules variations available with
me right now to test and share all the outputs.
Can we continue with all the IDs that I have inserted?
Or do you prefer to keep just the devices that I tested by myself until
now?
