Title:
  Cougar 200K keyboard not working properly with Gigabyte GA-970A-DS3
  motherboard

Status in linux-lts-utopic package in Ubuntu:
  New

Bug description:
  Keyboard working properly on Intel laptops  and during the boot
  sequence (ie I can use CTRL+ALT+DEL before linux boots).

  Once in linux ALT, CTRL and SHIFT on both left and right and Windows Key returns keycode 50 (keysym 0xffe1, Shift_L).
  CAPS returns  keycode 66 (keysym 0xffe3, Control_L).

  Tried various IOMMU combinations as the mobo has some issues with
  Linux and IOMMU.

  Collected logs are with IOMMU enabled in BIOS and 'iommu=allowed
  amd_iommu=on iommu=pt iommu=1' passed to grub.
