Hi,

Our CarrierBoard has miniPCIE for USB function.
We use Quectel LTE EC25-G,but can’t connect internet by Ubuntu modemmanager and Quectel’s tool (quectel-CM).

We use Quectel LTE EC25-G at ubuntu 18.04 for x86 is work fine.

BSP version:R32.3.1

Use ls /dev/cdc* command,that can found cdc-wdm0.
Use ls /dev/ttyUSB* command,that can found ttyUSB0~ttyUSB3.

Use AT mode commands are all work find.

Hi,

I am not sure about “Our CarrierBoard has miniPCIE for USB function.” Then this is a pcie interface but not USB.

Guess you need need extra driver to make it generate a ttyUSB interface. Unfortunately, we don’t have experience on modem so cannot share much help.

Maybe other forum users could share.

Hi WayneWWW,

Mini PCIe provides both the standard PCI Express and USB 2.0 signals.
The connect(interface) is miniPCIE,but signal is USB.

Thanks!
