Heads up for Yubikey owners, if you depend on OTP as opposed to FIDO2, #OpenBSD -current will no longer attach these devices as keyboards.
deraadt@ modified src/sys/dev/usb/ukbd.c: Most Yubikey ship with OTP support enabled out of the box (and generate accidental output like cccccblddbkhelgbdjuughbjdcvrddggdcjvricrriuk).
Yubikey re-configuration requires crazy buggy and fragile tools using crazy usb feature support, and therefore OTP disabling is very annoying.
We make a policy decision to not attach these as keyboards anymore, because a majority of users just want the FIDO functionality. If you want to use OTP, buy a different device from a different vendor or convince Yubikey to significantly improve their tooling.
