This has been an on going issue with my new Asus laptop. Frequently the keyboard isn't identified and I can't enter the decryption password. Frequently needing to attempt booting several times to get a working keyboard. So would seem to be a timing issue. For some time, Puppy's and some other linux distributions add hid module/s early in the boot process.
I would appreciate if this could be looked at for possible inclusion in EasyOS.
