<pre>I was expecting the following two mappings to behave the same way:
keyboard:dmi:bvn*:bvr*:bd*:svn*:pn*:pvr*
KEYBOARD_KEY_3a=leftctrl
keyboard:usb:v*p*
KEYBOARD_KEY_70039=leftctrl
However, the USB mapping will only work if the existing key is remapped, e.g.
keyboard:usb:v*p*
KEYBOARD_KEY_70039=leftctrl
KEYBOARD_KEY_700e0=capslock
It looks like the behaviour for USB keyboards is a bug.
I have tested this with systemd-208-16.fc20.x86_64 on kernel versions
3.14.2-200.fc20.x86_64 and 3.11.10-301.fc20.x86_64, as well as with
systemd-212-3-x86_64 on 3.14.2-1-ARCH.
The hardware I used includes a couple of USB keyboards, an old PS2 keyboard,
and the ThinkPad T520 keyboard.</pre>
