MiniPCIe based cellular modules supporting both USB2 and USB3 are not detected in the host system? Such as Sierra Wireless MC74** series, and Telit LM940/LM960 series modules.
From start the PCI-SIG miniPCIe form factor standard only included support for PCIe + USB2 data interface and had designated signal lines for these between host system and the miniPCIe module. Since revision 2.1 of the PCI-SIG miniPCIe standard it is defined that the PCIe data lanes can be shared/used for USB3 also.
Cellular modules mainly rely on USB2 interface but as the cellular throughput speeds have increased, the USB2 can become a bottleneck on LTE Cat 6 modules and higher. To address this, USB3 data interface was introduced on the higher data throughput mobile broadband cellular modules and made available in parallel to USB2 interface. However due to limited amount of pin lanes available in the miniPCIe socket they share location with the PCIe data interface pin lanes.
When the host system and module are powered on, the cellular module will try to probe if USB3 interface is present on the pin lanes and if communication can be established, otherwise the module will revert to using the USB2 data interface instead.
However, in some host systems where PCIe data interface also is implemented on the shared pin lanes, the signals will interfere with the cellular modules probing for USB3 interface making it not fall back to USB2 data interface. This usually result in the cellular module not being detected at all in the host operating system.
The USB3 auto-sensing functionality is enabled by default but can be disabled by using AT commands to write the memory changes to the internal NV memory which is stored between restarts. After the module is restarted it will use only the USB2 pin lanes for data interface. Please also check and validate if the host system BIOS support disabling of the PCIe interface in the miniPCIe socket.

Telit LM940/LM960 modules:
For Sierra Wireless MC74 series: (firmware version dependent)
For troubleshooting this issue in hardware, you can try isolating the USB3 data interface pins #23, 25, 31, 33 on the top side of the miniPCIe data cards card socket so no signalling to and from the hosts can occur. This could be done in the board design or with adapter.
How to step by step set up a data connection over QMI interface using qmicli and in-kernel driver qmi_wwan in Linux?
Several cellular modules based on Qualcomm chipsets implements the Qualcomm Qualcomm MSM (QMI) Interface.
There is a open source Linux in-kernel driver supporting this interface and it is called qmi_wwan. The library libqmi can be used to communicate with the cellular devices over the interface and do necessary configurations to trigger the data connection over the cellular network.
Sierra Wireless MC74**/EM74** series: requires RAW-IP configuration.
Sierra Wireless EM75** series: requires RAW-IP configuration.
Telit LM940: requires RAW-IP configuration.
Telit LN94x series: requires RAW-IP configuration.
Simcom SIM7500/SIM7600/SIM7600*-H series: requires RAW-IP configuration (supported in qmi_wwan driver kernel 4.18+).
Simcom SIM7100 series: 802.3 IP framing supported.
Sierra Wireless MC73**/EM73** series: 802.3 IP framing supported.
First install the libqmi Linux library e.g. by using your system package manager like apt etc. (more details about libqmi here: https://www.freedesktop.org/wiki/Software/libqmi/)
Verify that you have the Linux in-kernel qmi_wwan driver installed for the cellular modules exposed QMI interface endpoint over USB:
Can look e.g. like this:
|__ Port 1: Dev 3, If 2, Class=Vendor Specific Class, Driver=qmi_wwan, 480M
If the driver is not correctly loaded, please verify that the module is set to expose the correct USB endpoints configuration toward the host system and that you have followed the provided guides from the cellular module vendors, regarding how to implement the module in Linux.
Libqmi expose a command line interface that can be used to communication with the module over QMI interface.
The qmicli help will output information about all commands available:
The cellular modules QMI control interface are usually named cdc-wdm* e.g.:
In order to allow parallel commands to be execute on the module over QMI interface, it is recommended to use the libqmi proxy function. This can be done by including the attribute -p or --device-open-proxy in every qmicli command.
If a SIM pin is required for the SIM card, use command bellow:
qmicli --device=/dev/cdc-wdm0 -p --dms-uim-verify-pin=PIN,1234
The name of the related network interface to QMI control channel can be acquired with the command:
qmicli --device=/dev/cdc-wdm0 --device-open-proxy --get-wwan-iface
The most recent Qualcomm based cellular modules only expose QMI interfaces that can support Raw-IP mode. Sierra Wireless EM/MC74 and EM75 series modules, Telit LM940 and LN940 series for example require this.
Check what IP-mode the host system is configured for:
qmicli --device=/dev/cdc-wdm0 --get-expected-data-format
Check what IP-mode the cellular module require:
qmicli --device=/dev/cdc-wdm0 --device-open-proxy --wda-get-data-format
to change qmi_wwan driver to use Raw-IP.
Disable the network interfaces exposed by the cellular module:
ip link set dev wwan0 down
Trigger the Raw-IP support:
echo Y > /sys/class/net/wwan0/qmi/raw_ip
Enable the network interfaces again:
ip link set dev wwan0 up
Now the data connection in the cellular module can be activated e.g. with a IPv4 type configuration on the specified APN:
qmicli --device=/dev/cdc-wdm0 --device-open-proxy --wds-start-network="ip-type=4,apn=data.tre.se" --client-no-release-cid
Once "Network started" is displayed, you can send a DHCP request on the network interface.
Please note that not all DHCP clients in Linux can support Raw-IP format, udhcpc however support this for IPv4 over Raw-IP.
udhcpc -q -f -n -i wwan0
Disconnect the data bearer and data connection over QMI by command bellow and providing the network handle and CID returned at connection activation:
qmicli --device=/dev/cdc-wdm0 --device-open-proxy --wds-stop-network=NETWORK_HANDLE --client-cid=CID
Additional useful commands:
Request module manufacturer:
qmicli --device=/dev/cdc-wdm0 --device-open-proxy --dms-get-manufacturer
Get module model:
qmicli --device=/dev/cdc-wdm0 --device-open-proxy --dms-get-model
Get firmware version:
qmicli --device=/dev/cdc-wdm0 --device-open-proxy --dms-get-revision
Get module IDs (IMEI etc.):
qmicli --device=/dev/cdc-wdm0 --device-open-proxy --dms-get-ids
Get SIM card status:
qmicli --device=/dev/cdc-wdm0 --device-open-proxy --uim-get-card-status
Recent cellular modules like Sierra Wireless EM7565 require at least libqmi V1.20. Check version with command:
If the connection was successfully set up established, you now have data connectivity. A ping to a remote server using the cellular network interface can for example prove this:
ping -I wwan0 22.214.171.124
The ifconfig Linux tool can show the current details for the network interface:
libqmi is well integrated and supported in ModemManager tool for Linux. ModemManager again is well integrated and supported when using NetworkManager tool in Linux. Please note however that these two tools expect the cellular module interfaces to only be used by them so if you manually want to use the libqmi library or AT commands interfaces, please turn off/disable ModemManager and NetworkManager first.
The libqmi is a generic open source library for Linux systems and QMI protocol from Qualcomm, therefor there are several commands only working on selected devices and not necessarily on supported in the specific device you use, resulting in an error message.
