Hi, Thanks for your idea but unfortunately no... it did not change anything. It seems to me that the problem is more "power related" (see my comment on the laptop booting correctly on cold boot but ignoring the USB3 key and going directly to Grub Menu when reboot) Is there any parameter of the kernel that can put down the power of USB3 completely when xhci is unloading and that way, fake a "deplug" of the USB3 key ?
