Details:

I'm attempting to use the CentOS-7-x86_64-LiveGNOME-1511.iso image from a USB
stick via EFI. The image was downloaded and put on the stick using dd
if=xxx.iso of=/dev/sdb . 

I have a Logitech K120 keyboard on a USB 1.1 interface. On selecting "e" from
the Grub menu to edit out "quiet rhgb" from the relevant command, all goes
well until I attempt to then execute the resulting commands using Ctrl-X.
Instead of executing the commands it instead inserts x.

Similarly attempting to access a command prompt using Ctrl-C instead results
in inserting a C.

The result of lsusb -v edited to just show the relevant device is shown
below.

If I just boot without attempting to edit the command, it boots fine (but
obviously with quiet and rhgb).

If I install grub2 by the usual methods, not using EFI, it works fine.

If you need any further information (that I don't yet know how to get hold of)
please let me know.

With thanks in advance.
