Access Pixel 2 XL "taimen" through ADB (while in the process of installing lineageOS)

I followed [this guide](https://wiki.lineageos.org/devices/taimen/install) until fastboot flash boot boot.img included and OK Then reboot in recovery mode Then *"Now tap Factory Reset, then Format data / factory reset"* included and OK **/!\\** BUT since then, _adb_ can't see my Nexus phone (Pixel 2XL - "taimen"), neither is it visible with lsusb when in recovery mode. I tried *"Apply from ADB"* or *"Enable ADB"* via lineageOS recovery mode gui, but adb devices returns an empty list :-| When in fastboot mode, I can see the phone via lsusb :

[stan@stan-xps139305 ~]$ lsusb
...
Bus 003 Device 012: ID 18d1:4ee0 Google Inc. Nexus/Pixel Device (fastboot)
...

Is there a way to get my phone recognized by _adb_, or to flash it via _fastboot_ directly... ? Also can _udev rules_ help... ? N.B. : SECURE BOOT is ON (don't know if it can be blocking...) [EDIT] >>> I also tried several USB cables/ports already :-| I'll try on another computer too ASAP I just fear the phone USB mode is kinda stuck while in recovery mode. This page shows the possible modes for pixel phone (mine is PIXEL 2 XL): [https://devicehunt.com/view/type/usb/vendor/18D1](https://devicehunt.com/view/type/usb/vendor/18D1) 4ee2 instead of 4ee0 is what I expect, but hell no. How is it that I can see the phone with lsusb while in fastboot mode, but cannot see it at all while in recovery ? >> these are the _udev_ rules I've set:

#GOogle Inc. 
SUBSYSTEM=="usb", ATTR{idVendor}=="18d1", ATTR{idProduct}=="4ee0", MODE="0666", GROUP="plugdev"
SUBSYSTEM=="usb", ATTR{idVendor}=="18d1", ATTR{idProduct}=="4ee1", MODE="0666", GROUP="plugdev"
SUBSYSTEM=="usb", ATTR{idVendor}=="18d1", ATTR{idProduct}=="4ee2", MODE="0666", GROUP="plugdev"
