Initrd doesn't contain the new 'hid-logitech-hidpp' module. More information: http://forums.fedoraforum.org/showthread.php?t=303722
My keyboard started working on boot after I had created a file (logitech-kb) containing Logitech's keyboard modules to /usr/share /initramfs-tools/modules.d/ and reinstalled the broken kernel. ** Attachment added: "logitech-kb" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1448519/+attachment/4398620/+files/logitech-kb -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1448519 Title: Logitech K400 cannot type in LUKS passphrase at boot Status in linux package in Ubuntu: Confirmed Bug description: After upgrading to Xubuntu 15.04 (which uses the linux- image-3.19.0-15-generic kernel), I can no longer type in my LUKS passphrase (or even press Control-Alt-Delete to reboot the machine) at boot using my Logitech K400 wireless USB keyboard. Thankfully, the linux-image-3.16.0-34-generic kernel (which does not suffer from this problem) still existed on my machine from my previous Xubuntu 14.10 installation. So I am using that kernel as a workaround: 1. Boot the computer. 2. Wait for the BIOS splash screen to pass. 2. Quickly press the Escape key repeatedly until the GRUB boot menu appears. If I don't do this quickly enough, I encounter the LUKS passphrase screen where my Logitech K400 wireless USB keyboard does not work. 3. Press the Down arrow key to choose the second menu item called "Advanced Ubuntu Options". 4. Press the Down arrow key several times to choose the menu item called "linux-image-3.16.0-34-generic". 5. Press the Enter key. 6. Now the LUKS passphrase screen will appear where my Logitech K400 wireless USB keyboard will work correctly because the linux-image-3.16.0-34-generic kernel was booted instead of the problematic linux-image-3.19.0-15-generic kernel. Please fix the linux-image-3.19.0-15-generic kernel's build recipe to include support for the Logitech K400 wireless USB keyboard. Thanks for your consideration.
