I've tried three different USB keyboards on an A20-Olinuxino-Micro and a Banana Pi, and I always get that error "cannot reset port N!?" where N is whichever USB socket I've plugged it into, and U-Boot cannot see the keyboard. Once Linux has loaded, the keyboard works without any trouble. Can anyone suggest what is causing this? Thank you, B.R.
