[SOLVED] Dock hotplug does not work

[ngahy]

Hello everyone,

I am using a Dell Precision 7560 with a Dell Dock Station WD19DCS.

The dock seems to work fine when I boot the computer with it plugged-in.

I have two monitors, a webcam, a keyboard, a mouse and an ethernet cable plugged
in it. The only functionnality that seems to work is charging my computer.

When I boot my computer with it, everything seems to work fine except the two
monitors that are detected but without any display (I tried many thing with
xrandr but always black screen. If I am lucky, it works like hours after my last
xrandr command and I do not know why).

When I unplug then plug the dock, only the charging works: ethernet does not
work anymore, the mouse sometimes work but not always. I think the hotplug does
not work well, even if I enabled everything related to it in the Kernel. I tried
to enable Type-C features and USB4 (which is for Thunderbolt in the Kernel) but
I still have the same issue: two monitors, an external keyboard, a mouse,
ethernet cable, all not working. The dock is only charging.

The Dock option is enabled in the Kernel. The mouse and keyboard is detected
when doing lsusb, but they are not working, unless I reboot.

Here is my kernel configuration: https://pastebin.com/iRHgLTk2
Output of lspci -vv: https://pastebin.com/H3u9AMBv

Can you help me solve this issue? Thank you

I tried a sys-kernel/gentoo-kernel-bin:5.10.61 and it worked. I compared the configuration with mine
and looked at the needed drivers using linux-hardware (https://linux-hardware.org/), then enabled them
