Re: Initrd and USB Keyboard

Hello,
i was also fighting with the same issue after upgrading to newer kernel. The wiki https://wiki.debian.org/Keyboard#How_to_enable_USB_keyboard_in_initramfs helped me to figure out the problem. In short:

1. identify all kernel modules your USB keyboard is using/depends on

2. add those modules to /etc/initramfs-tools/modules file

3. run update-initramfs -u

For my Lenovo USB Compact keyboard following modules were necessary to add so that i was able to type LUKS password at boot using the keyboard:
usbcore
usb_common
usbhid
hid
ehci_pci
xhci_hcd
ohci_hcd
uhci_hcd
ehci_hcd
hid_generic
hid_lenovo

HTH,

Stano

You probably are missing hid_generic. You need either that module or
evdev (iirc) for input (hot/cold)plugging to work. Even with those
modules, I still haven't been able to access the usb keyboard connected
through my laptop's docking station, though, so this may not be the
complete answer.

Arno
