[Solved]Wireless keyboard not working with kernel param init=/bin/bash

Hi. I have a wireless keyboard Logitech K350. When I boot my computer, I can use the keyboard immediately - I can use it in BIOS, I can use it to 'show the boot menu', I can use it in Grub 2, and lastly, it all works when Arch has booted completely.
However, it doesn't work if I load the kernel with the switches 'init=/bin/bash' or 'rdinit=/bin/bash' - why might that be? Is it something missing in my initramfs? Is this something also used when rdinit=/bin/bash and not simply the default /init?

Your bios has USB support. The Linux kernel does not until you load the appropriate module. You can add the keyboard hook to your initramfs, but this still won't give you a keyboard if you specify rdinit= because nothing will have loaded the module.

Ok thanks. I was aware that it might not work with rdinit.
I must eventually read the mkinitcpio wiki page, it has been on my todo list for too long ;d
I will mark it as solved as solved as it was more a theoretical question and I got an answer.
