Cryptsetup prompt appears before the keyboard gets detected

So I'm using LUKS encryption with the sd-encrypt hook. What happens is that the password prompt appears before the keyboard has been detected, and my keyboard presses don't get registered for about 5 seconds, is there a way to make the keyboard appear faster, or make the password prompt always appear after the keyboard has loaded?

I'm using the linux kernel.

Relevant log:

Re: Cryptsetup prompt appears before the keyboard gets detected

$ grep ^HOOKS /etc/mkinitcpio.conf

What's the order?

Re: Cryptsetup prompt appears before the keyboard gets detected

You can try adding required usb/keyboard modules in mkinitcpio.conf MODULES (will be translated to /etc/modules-load.d/MODULES.conf you can see in lsinitcpio) and see if it gets loaded earlier that way.

Here you go:

HOOKS=(base systemd autodetect microcode modconf keyboard sd-vconsole block sd-encrypt filesystems fsck)

I've tried these, with no success:

MODULES=(usbhid hid_generic xhci_hcd)

Re: Cryptsetup prompt appears before the keyboard gets detected

Does the same also happen if you use linux-lts?

Re: Cryptsetup prompt appears before the keyboard gets detected

I have tried three kernels: linux, linux-lts, and the cachyos kernel. I've also noticed that adding those kernel modules to the initramfs does improve the speed of keyboard initialization, which I hadn’t noticed before. However, it still feels like a half solution, since the keyboard loads after the password prompt appears. Ideally, I would like the password prompt to always appear only after the keyboard has fully loaded, no matter how long it takes. I’d appreciate it if anyone has a solution like that.

Re: Cryptsetup prompt appears before the keyboard gets detected

I added loglevel=7 to the kernel parameters and noticed that it hangs on a specific part:

You can run 'dmesg' later to get the same output, with timestamps.

kernel: usb 1-5.1: new full-speed USB device number 6 using xhci_hcd          <--- Hangs on this line

So this line appears and then it hangs (how long?) or it hangs before this line appears?

You seem to have the keyboard plugged into a hub. Did you try connecting it directly to the motherboard?
