Problem: Running kernel 3.11.0-12-generic after a Ubuntu upgrade from 13.04 to 13.10 my USB keyboard is not recognised, thus I am not able to unlock my encrypted disk. I suspect it might be related to a minimal/incorrect install of initrd.

Question: How do I go about getting the newest kernel to recognise my generic USB keyboard, allowing me to unlock my encrypted disk?

What I have tried: I have already re-installed the newest kernel:

sudo apt-get install --reinstall linux-image-generic linux-image

and I have also updated the initrd:

update-initramfs -c -k 3.11.0-12-generic

Back story: I just completed upgrading my Ubuntu system from 13.04 to 13.10. When I subsequently rebooted by system I was no longer able to enter my encryption password (passphrase) as the keyboard drivers did not load.

Temporary workaround: Earlier in the boot process (before the keyboard stops working) I was able to enter GRUB menu were I choose to boot from an older kernel (3.8.0-31-generic) which did load the USB keyboard drivers. This is currently the kernel I am running.

Thanks

Add ohci_pci to /etc/initramfs-tools/modules and save

sudo update-initramfs -u

Reboot and Enjoy! :-)
