Just from the log, it seems that the modem is not in rmnet mode.
Maybe it need a restart.

FKA · May 20, 2025, 12:42pm

It is restarted every time it is unplugged and repowered, isn’t it?
It ist an miniPCI-Card attached on an USB - miniPCI-Adapter. An SIM is not yet equipped.

Bean.Wang-Q · May 20, 2025, 12:58pm

[03-13_13:46:59:423] unsupport software_interface 1

it means that it is not in rmnet mode.

AT+QCFG=“usbnet”
results in
+QCFG: “usbnet”,0

AT+QCFG=“usbnet”,1
results in
OK

AT+CFUN=1,1
afterwards results in
+CME ERROR: 3

So i am not even able to switch to another mode than 0 (QMI or RMNET mode).

Bean.Wang-Q · May 21, 2025, 12:50am

AT+QCFG=“usbnet”,0
And restart the module, and then check it again.

Still the same.

Is anything else to do than enable the following kernel config options?
CONFIG_USB_SERIAL_OPTION=y
CONFIG_USB_NET_QMI_WWAN=y

Bean.Wang-Q · May 21, 2025, 12:31pm

It has nothing to do with the kernel driver. The driver qmi_wwan is already and it should be working.
The problem is the modem seems not configured correctly.

As nothing has changed, the output is still the same:

Is there a Firmware-Update for the device?

FKA · May 22, 2025, 12:46pm

From the source of questel-cm:

if (profile->software_interface == SOFTWARE_ECM_RNDIS_NCM) {
    dbg_time("Modem works in ECM_RNDIS_NCM mode");
    profile->request_ops = &atc_request_ops;
    profile->qmi_ops = &atc_dev_ops;
    ret = qmi_main(profile);
}
else {
    dbg_time("unsupport software_interface %d", profile->software_interface);
}

So RNDIS ( AT+QCFG=“usbnet”,3 ) is the right setting?

FKA · May 22, 2025, 2:07pm

I do not have the qmi_wwan_q.c file yet. Can you send it?

No. It only support usbnet 0 and 2.
