Description Robert Buchholz 2012-02-01 01:23:13 UTC

Description of problem:
Since upgrading Fedora 16 from kernel 3.1 to kernel 3.2 (3.2.2-1.fc16.x86_64 specifically), the keyboard is not usable at the boot prompt anymore. It is usable in Grub before and in the console after booting.

The reason seems to be that since Kernel 3.2, the USB device has its own driver to support multiple hid devices from one usb device (hid_logitech_dj) and does not use the regular usbhid anymore:

Workaround:
In /etc/dracut.conf set
 add_drivers+="hid_logitech_dj"
and then run
 /sbin/dracut -f /boot/initramfs-3.2.2-1.fc16.x86_64.img 3.2.2-1.fc16.x86_64


Version-Release number of selected component (if applicable):
kernel-3.2.2-1.fc16.x86_64
dracut-013-20.fc16.noarch

How reproducible:
always

Steps to Reproduce:
1. Plug in Logitech keyboard with Unifying Receiver
2. Upgrade to Kernel >=3.2
3. Reboot
  
Actual results:
Cannot enter password in initramfs

Expected results:
Keyboard is usable in initramfs

workaround for F16:

edit /etc/dracut.conf:

add_drivers+=" hid-logitech-dj "


F17/rawhide dracut version has it hardcoded right now.
