No usb device can be found

Installing and Using OpenWrt Network and Wireless Configuration
1

In connection to https://forum.openwrt.org/t/tether-internet-access-from-my-mobile-phone-is-lost/206956 i have upgraded to OpenWrt 24.10.0 and i have lost the usb tethering. i have looked to create again the interface but i do not see any usb0 or usb1 interfaces available

`root@OpenWrt:~# ip link show dev usb0
ip: can't find device 'usb0'
root@OpenWrt:~#
root@OpenWrt:~# ip link show dev usb1
ip: can't find device 'usb1'
root@OpenWrt:~#`

and here is my cat /sys/kernel/debug/usb/devices

any ideas, please?

logread -f while reconnecting the phone to the router, post it if needed.

don't upgrade further, USB tethering appears to be broken in .1 and .2, at least for me.

there's also USB Networking: USB to ETH device name behavior change.

Just follow https://openwrt.org/docs/guide-user/network/wan/wwan/ethernetoverusb_rndis
and pay attention to the following:

After installing the packages and connecting the USB stick, the following should appear in dmesg output:
[...]
Note the device name (usb0 ) mentioned on the last line, it will be used later. For another modem the name could be eth2 or something like that.

The same on https://openwrt.org/docs/guide-user/network/wan/smartphone.usb.tethering page:

  • click on Status and then on System Log to see this log from the LuCi web interface

  • or use dmesg command on the console over SSH
    [...]
    Note the interface name (usb0 ) mentioned on the last line, this is the name to use during the setup process.

i had the rndis packet already. Here is my dmesq
