hi,
I have RPI4 running OpenWRT,
trying to use ZTE MF79U LTE modem for wan connection.
followed all instructions about adding usb modem interface.
lsusb: ...ID 19D2:1405 demo, Incorporated DEMO Mobile Boradband
but dmesg only recognize CD-ROM and MMC storage
in ifconfig no usb0
I used this instructions:
If the OS only sees the cdrom, it's usually because of an issue with usb-modeswitch.
the product ID is correct.
look like the modem didn't switched to the correct mode
ZTE MF79U , LTE Cat 4, 4G Wingle on OpenWrt 21.02.3 r16554 on ath79 device
Hello,
Thanks for your support!
After some research I am stuck on the missing configuration of MF79U in usbmodswitch. Indeed, when inserting the 4G LTE usb modem, it registers eth2 then unregisters it in favor of usb storage...
Would you have a track to have a good config to switch please or any other clue ?
Thanks in advance !
I added this missing entry which is not working. https://www.draisberghof.de/usb_modeswitch/ChangeLogData :

Hello,
thanks for the advices
After some research and testing I finally found the right entry
I added this entry in
/etc/usb-mode.json
"19d2:1225": {
"*": {
"t_vendor": 6610,
"t_product": [ 5125 ],
"mode": "StandardEject",
"msg": [ 34 ]
}
},
Now it works!

[ 14.767217] cdc_ether 1-1:1.0 eth1: register 'cdc_ether' at usb-1e1c0000.xhci-1, ZTE CDC Ethernet Device
....
I also have the same device. Does this put it into "modem only" mode?
For me it works as a ethernet device but I would like to avoid double nat so I was looking if it is possibile to use it as a modem only.
Have you found a solution?
See if you can temporary switch it. Login to your modem web interface and then open
http://192.168.0.1/goform/goform_set_cmd_process?goformId=USB_MODE_SWITCH&usb_mode=8
Adjust the modem IP if necessary.
Check if anything has changed in cat /sys/kernel/debug/usb/devices output.
I just bought this modem and I'm waiting for arrive. This option you mentioned can define it permanently? Or only for that session?
That will be a temporary change, however if it works and composition is switched, then it should be possible to make a permanent change.
If the mode cannot be switched using the http method, then there is a Windows tool called scsi.exe that can do almost the same.
Initially the modem is in mode 0 and the goal is to switch it to 1.
AT+ZMODE=0 # RNDIS + MMC & CD
AT+ZMODE=1 # RNDIS + MMC & CD + ADB + Modem + AT & LOG interface
Once adb interface is exposed it should be possible to access the modem with adb shell and see whether it is possible to change its composition to something different from RNDIS.
Unfortunately I do not have a suitable modem to experiment with, so I can only share what is in my notes.
Check what do you have in cat /sys/kernel/debug/usb/devices output in OpenWrt (with modem plugged in). If you have a storage component there - use usb_modeswitch to eject it as shown above and re-run cat ....
Hey, AndrewZ, a kind off topic, but my modem arrives today and it was working perfectly. I even did some speed tests, but now it stop working!
The LED is red and when I try to open settings page, I just got limited service. I tried with two carriers, but no success 
Do you have any idea what things could be happened?
