iPhone not recognized - Xiaomi MiWifi Mini - 21.02-RC1

I didn't use my router for a while but it worked well with my iPhone. I decided to upgrade it to v21.02-RC1 in order to have support for iOS 14. However, I'm having a recognition issue. I followed wiki for smartphone USB tethering and installed all packages. usbmuxd is running (check with ps). When I plug my iPhone, nothing is showing up and when I list usb devices using lsusb, iPhone is not listed:

root@MiWifiMini:~# lsusb -t
/:  Bus 02.Port 1: Dev 1, Class=root_hub, Driver=ohci-platform/1p, 12M
/:  Bus 01.Port 1: Dev 1, Class=root_hub, Driver=ehci-platform/1p, 480M
    |__ Port 1: Dev 16, If 0, Class=, Driver=, 480M
[  513.810132] usb 1-1: new high-speed USB device number 16 using ehci-platform


 1804 root      4040 S    /usr/sbin/usbmuxd --systemd

I did test with an iPhone running iOS 10, another one running iOS 13 and the last one running iOS 14. No iPhone is recognized.

Any ideas ?
