Iphone tethering - won't even recognize my iphone

Hello I am using openwrt with the Nanopi R2S, Version:

|Firmware Version|OpenWrt SNAPSHOT r15871-bb817bb4b8 / LuCI Master git-21.050.34860-b8d2bcd|
|Kernel Version|5.4.99|

When I plug in my iPhone8 into the R2S, the system won't even recognize it, dmesg shows:

[   12.612225] r8152 4-1:1.0 eth1: Promiscuous mode enabled

And it's not even shown in lsusb:

I have tested the iPhone tethering with my PC and the odroid N2 board, they all works perfectly, thus it should not be the problem of my iPhone and cable.
Also I have tested pluging in a usb storage device, the nanopi R2S would recognize it perfectly. Thus the problem should lie in the openwrt software.
Also I have tried using a usb hub that support external power, but the same problem persists, thus I think it's not the issue of powering.

Thank you for your reply,

But that's not my case. In that case, the iPhone can be recognized but just cannot use the internet. I have faced that problem in early time. To prove that I have enough knowledge about it, the repository Iphone_usb_tethering_fix is created by me to fix this issue for Linux devices that can build the ipheth module locally.

But in my case the system does not even know what has been plugged into it. Stopped at reporting:

usb 1-1: new high-speed USB device number 8 using ehci-platform

does lsmod | grep ipheth show a line like this
ipheth 16384 0

does dmesg | grep ipheth give a similar line as result (with no iphone connected, this is just the message when the module is loaded on boot)

[ 8.483567] usbcore: registered new interface driver ipheth

If you don't see either (or both) the module is not loaded

Also try removing usb-modeswitch with opkg remove to make sure it's not interfering with the detection. I have seen it cause problems with Android phone tethering in the past.

I have removed usb-modeswitch, it still does not work, a reboot won't either work.
lsmod | grep ipheth shows:

ipheth                 20480  0

And dmesg | grep ipheth shows:

[    8.994987] usbcore: registered new interface driver ipheth
