#135 Thinkpad X200 Unknown key 0xFF

Hello,

On my Thinkpad X200, with Libreboot (grub libgfxinit corebootfb frazerty) version 20221214 and 20220720, when I turn on my laptop with my keyboard (Logitech K120) plugged in my ultrabase and my laptop plugged on my ultrabase, it says "Unknown key 0xFF detected" many times, then I can't reach the menu with "Load Operating System".

It doesn't happen with 20211122. It doesn't happen either when the keyboard is plugged directly to the laptop.

Thanks for your help!

this bug has been in libreboot pretty much since the project started. if someone can debug this in grub that'd be great

doesn't always happen, but when it does happen, it's when plugging in an external usb device in grub

Thanks for answering. I will just try every new update and hope it doesn't happen at some point.

It's surprising that this would be a grub bug that not always affects libreboot. As if something could be done about it within libreboot.

In case it is useful : the bug did not happen on 20211122, happened on 20220720 and 20221214, and doesn't happen on 20230423.
