If you can add the packages … I can test them on my system to see if its working or not…
Same time I can give you a full access to my system PC to control and to see … To reach to our goal …
These my packages are installed on OpenWrt system
I used these packages to get network mostly throgh modemmanager package wheich is available on your system but system can detect the modem
Only openwrt packs the kernel modules in packages…normal linux does not have this…i’m not sire if it works when i compile the module and only give you the ko files…but i can add the options and give you the full kernel package (tar.gz) to unpack in current debian image.
Which kernel do you use? 6.9-main?
kmod-mhi-net
kmod-mhi-wwan-ctrl
kmod-usb-serial-wwan
kmod-usb-net-qmi-wwan
kmod-usb-acm
kmod-usb-net-rndis
kmod-usb-dwc3 //really needed?
kmod-usb-cdns3 //really needed??
kmod-mhi-wwan-mbim
kmod-usb-serial-qualcomm
kmod-usb-serial-option
kmod-mtk-t7xx
kmod-usb-core //should already be builtin my kernel
kmod-usb-net-cdc-eem
Are the mhi packages, the mtk t7xx and the dwc3 driver really needed?
please note in first post that adding the nat table/rule only works when having the other chains (input,output,forwarding) present…or just use the rules from my images repo
