I must plug an external keyboard+mouse on Lenovo V15 Gen 4

[Jean-Marie Tschanz]

Hello everyone, I'm Jean-Marie, my journey with linux has just started.

So I can't use my touchpad and keyboard on this new Lenovo V15 Gen 4
"cat /proc/bus/input/devices"

doesn't show

"I: Bus=0011 Vendor=0002 Product=0007 Version=01b1
