With reference to this
thread from getting the module for the Logitech K750 into initramfs originally.
It is the same problem really, i.e. keyboard works in Grub and at login, but i cannot enter password at cryptsetyp although a wired USB keyboard works fine.
user-001@elrond ~$ lsinitrd /boot/initramfs-$(uname -r).img | grep logitech

So the module loads, it just doesn't seem to work, and I have issued "dracut -f
" just for fun but the keyboard still refuses to work at the cryptsetup prompt and the unifying receiver was plugged in during the kernel update.
Also this still seems to be the case in 3.19.2 kernel.
I suspect somethings broken in the kernel - perhaps?
