Hint: try another USB port.
USB is like a network, and it could be a jungle of cables and ports and switches and bridges and whatnot. But the closer you get to the mainboard, the better are your chances to escape such a problem.

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

This worked. Apparently I had all the usb devices connected to the same controller and it seems linux initialises them controller by controller. Thanks
I had an issue where one keyboard (worked with another one) worked in bootloader, but not when entering the encryption password after that. I believe I solved that by moving keyboard earlier in the module list in mkinitcpio.conf. Maybe something similar would solve your issue?
I did try messing with the hook order but it's already as early as it can be.
I had a motherboard like this: the USB ports didn't work until it booted into an OS. You had to connect a PS2 to make changes in the BIOS, and could only boot from IDE. It was super-annoying.
Yep if the MB has a PS/2 slot this is the solution.
You can also get a usb to PS/2 converter so you don't need an extra keyboard.
Check if you find anything about this in the kernel log (dmesg).
Are you using the usb ports on the motherboard itself? Because you need to with a lot of MBs depending on when they initialize other USB
...on which hardware?
Last i encountered this issue i had to connect it directly to an USB port, instead of through an USB hub.
I've had this happen before on some weird systems. Unplugging and replugging the keyboard woke the keyboard back up.
Was there no option about it on the BIOS/UEFI about something like that?
How would bios change how linux loads usb devices?
You never know how the kernel would behave compared to how the BIOS is setup. There might be some bios settings that force the kernel to behave a specific way.
There are lots of BIOS options that impact USB devices, and especially input devices. I'd start digging. If anything, I'd try plugging into the USB ports that are connected to the main bridge at the top of the board, and not any that are extended via passthrough cable. On some boards, those USB ports are set to emulate PS2 serial.
I believe this is a hardware issue. Have you checked the USB options in the BIOS?
It works fine in bios and bootloader. This only happens during boot
Your title indicates otherwise so might be worth amending it.
