TECHSHIP IS A GLOBAL SUPPLIER OF WIRELESS COMPONENTS
The Huawei MS2372h-517 LTE USB stick is a robust, industrial 4G USB dongle. The MS2372h is a LTE CAT-4 modem with Hisilicon chipset for use in the North American region and enables the exchange of data with a transmission speed of up to 150 Mbps (D/L) and 50 Mbps (U/L).
The Huawei MS2372 can be easily controlled by using standard AT commands. In addition to the built-in diversity antenna the MS2372 also has the possibility to be connected to one or two external antennas via its two CRC9 connectors.
This archive contains the Linux driver package for MS2372 series modules. It can be used to assure the module have the drivers correctly set up if the in-kernel drivers do not load properly for the module and e.g. USB mode change is failing.

How to activate the data connection for Huawei cellular modules over the USB network interface in Linux?
The first step is to assure that the Huawei cellular module is properly loaded in the Linux system. Huawei modules are most often automatically detected in recent Linux kernels, this can be verified in different ways by commands bellow:
The lsusb command shows what physical USB devices are detected in the Linux operating system:
Bus 001 Device 003: ID 12d1:15c1 Huawei Technologies Co., Ltd.
The lsusb -t command shows the USB endpoints exposed by the detected USB devices and the related drivers loaded for them:
/: Bus 01.Port 1: Dev 1, Class=root_hub, Driver=ehci-pci/6p, 480M
|__ Port 1: Dev 3, If 0, Class=Communications, Driver=cdc_ether, 480M
|__ Port 1: Dev 3, If 1, Class=CDC Data, Driver=cdc_ether, 480M
|__ Port 1: Dev 3, If 2, Class=Vendor Specific Class, Driver=option, 480M
|__ Port 1: Dev 3, If 3, Class=Vendor Specific Class, Driver=option, 480M
|__ Port 1: Dev 3, If 4, Class=Vendor Specific Class, Driver=option, 480M
|__ Port 1: Dev 3, If 5, Class=Vendor Specific Class, Driver=option, 480M
|__ Port 1: Dev 3, If 6, Class=Vendor Specific Class, Driver=option, 480M
The dmesg lists all the driver loading logs since system boot up:
usb 1-1: new high-speed USB device number 3 using ehci-pci
usb 1-1: New USB device found, idVendor=12d1, idProduct=15c1

cdc_ether 1-1:2.0 ens35u1c2: renamed from usb0
IPv6: ADDRCONF(NETDEV_UP): ens35u1c2: link is not ready
cdc_ether 1-1:2.0 ens35u1c2: kevent 12 may have been dropped
The command ifconfig -a will list all network interfaces loaded in the Linux system, the cellular module interface can be named differently depending on the distribution used but generally named wwan0 initially.
ens35u1c2 Link encap:Ethernet HWaddr 02:1e:10:1f:00:00
UP BROADCAST MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)
the command ls can list the USB serial interfaces detected:
/dev/ttyUSB0 /dev/ttyUSB1 /dev/ttyUSB2 /dev/ttyUSB3 /dev/ttyUSB4
Once this far we can now start communicate with the cellular module over AT commands. There are different applications available in Linux that enables manual communication with serial interfaces:
minicom -D /dev/ttyUSB2
socat - /dev/ttyUSB2,crnl
Basic AT commands to set up the data connection:
Print general information about cellular module
Enter the SIM PIN code
Set the operator APN name to use for the data connectivity
Activate the data connection for the network interface exposed to host system with the APN profile previously created.
Once ^NDISSTAT:1,,,"IPV4" is received you now have a active data connection to the network operator.
Now you can use a DHCP client in your host system to request an IP address from the cellular network:
dhclient -v ens35u1c2
Listening on LPF/ens35u1c2/02:1e:10:1f:00:00
Sending on LPF/ens35u1c2/02:1e:10:1f:00:00
Sending on Socket/fallback
DHCPDISCOVER on ens35u1c2 to 255.255.255.255 port 67 interval 3 (xid=0xf1045e28)
DHCPREQUEST of 18.104.22.168 on ens35u1c2 to 255.255.255.255 port 67 (xid=0x285e04f1)
DHCPOFFER of 22.214.171.124 from 126.96.36.199
DHCPACK of 188.8.131.52 from 184.108.40.206
bound to 220.127.116.11 -- renewal in 235255 seconds.
You now have a working cellular network data connection in your Linux system.
How to collect initial diagnostics data and logs for Huawei cellular modules needed when requesting Techship technical support?
In order to troubleshoot and solve a technical problem, we ask you to please provide information about your system and logs from the related Huawei module when creating a technical support ticket.
Problem description of what exact problem is and in what precise situations present
Describe the host system:
-Hardware (system board, peripherals...)
-Operating system and detailed versions (E.g. Windows, Linux release, kernel...)
-Drivers and driver versions
Identify the precise details of cellular module found on label:
-SKU/BOM or P/N code
(For RMA returns the IMEI number is required also)
If you are running on a Linux based system, please capture the terminal logs bellow:
ls -l /dev/serial/by-id
ls -l /sys/bus/usb-serial/devices
The logs from module firmware can be acquired by accessing one of the USB enumerated serial (COM) interfaces accepting AT commands. (In Windows this is the PC UI serial interface). Send the following commands to module and capture the text output and include them when creating the the technical support ticket.
The support ticket can be created after login at: https://techship.com/technical_support/
