usb keyboard does not work for entering decryption passphrase at boot
I have a T420 thinkpad that I use as a desktop with monitors and usb keyboard hooked up. I am running vanilla 4.14 kernel. My HDD from a recent install is LUKS encrypted - just followed the wiki. When I boot and get to the screen to enter my decryption passphrase, my usb keyboard does not work (no input is detected). My laptop keyboard works fine. Then when the OS loads my usb keyboard works fine. My problem is very similar to this forum post and some others. The difference is, I have the keyboard hook in front of encrypt (and autodetect), I have tried putting everything that post has in modules in modules (i915 ext2 ext4 ehci_pci usb_common xhci_hcd uhci_hcd ehci_hcd ohci_hcd usbhid usbcore hid_generic), and I am not regenerating the wrong image by accident like that post as I have been using mkinitcpio -P each time. The usb keyboard uses the usbhid driver. With the keyboard hook in an early position and all of those modules loaded, that the problem still persists is baffling.
It may be worth noting that while the usb keyboard works fine in the OS, it also does not work at the grub menu for choosing an image or in the BIOS. (As a preemption, the BIOS does not, for some reason, and never has had a USB Legacy Support switch.)
I would greatly appreciate any thoughts on avenues I might explore to get this settled!

Re: usb keyboard does not work for entering decryption passphrase at boot
It should work if you really have the required modules loaded. If it works without autodetect, that should be it...
Show lsmod when it works? vs. lsmod in the initramfs shell.

Re: usb keyboard does not work for entering decryption passphrase at boot
Well, so the laptop's keyboard always works in all contexts, but the usb keyboard always works once the OS is loaded, and never works at the decryption passphrase screen or the grub menu that follows, regardless of whether the autodetect hook is used or not. When I am in the OS with everything loaded and the usb keyboard working, my lsmod looks like this:
