Live debian testing boots without mouse and keyboard

Hi,
I am trying to set up a multiboot USB key with refind, mainly to have such a tool for install parties but also to try to learn things about EFI/GRUB/rEFInd ecosystem. I have [almost succeeded](https://blog.tremplin.ens-lyon.fr/Ge...tiboot-en.html) and everything works perfectly for : buster, linux_mint, ubuntu, manjaro. but things are not working for bullseye debian-live-testing-amd64-gnome+nonfree.iso...
If I boot the iso on an usb key everything is OK.
If I unpack the iso on one of the partitions with the command Code:7z x debian-live-testing-amd64-gnome+nonfree.iso -o/media/user/***-**** and add the following menuentry in rEFInd (identical to the one for buster except kernel numbers)

Code:menuentry BullsEye {
icon EFI/BOOT/ICONS/os_linux.png
volume d22826a0-e155-4be2-b5d0-############
loader live/vmlinuz-5.4.0-4-amd64
initrd live/initrd.img-5.4.0-4-amd64
options "boot=live components splash quiet root=UUID=####-#### "
submenuentry "Debian Live with French (fr) Support" {
add_options "locales=fr_FR.UTF-8"
}
submenuentry "Installeur graphique debian" {
linux d-i/gtk/vmlinuz
options "append video=vesa:ywrap,mtrr vga=788 root=UUID=####-####"
initrd d-i/gtk/initrd.gz
}
}The laptop boots, opens the debain live user screen but mouse and keyboard are not accessible. I tried other mouse and keyboard without success. The USB-C is not loaded (no wired network).
My feeling is that the USB is not detected am I missing an option on the kernel command line.

I have not been able to boot with the Code:/media/user/####-####/EFI/boot/grubx64.efi from the rEFInd menu.

Thanks
