Questions[microsoft-keyboard](ubuntu)

I'm trying to remap LCtrl and CapsLock on my Microsoft Wired Keyboard 600 with HWDB but for whatever reason the system does not see the changes that I make.

This is how my hwdb rule looks like:

evdev:input:b*v045Ep07F8*
 KEYBOARD_KEY_3a=leftctrl
 KEYBOARD_KEY_1d=capslock

The vendor and the model codes come from lsusb and were reconfirmed in /sys/devices/pci0000:00/*

After copying the config file to /etc/udev/hwdb.d, running systemd-hwdb update and issuing udevadm trigger no changes in the keyboard config are present.

I've also tried:

• Rebooting — didn't help.
• Specifying the bus explicitly as 0003 — didn't help.
• Confirming with evtest that the key codes I'm using are correct for my keyboard — yep, those are the correct keycodes.
• Confirming the applied rules are listed in sudo udevadm info /sys/class/input/eventX — yes, the new rules are listed, which should mean they were applied successfully? Yet the keys behave the same way they did before.

E: KEYBOARD_KEY_1d=capslock
E: KEYBOARD_KEY_3a=leftctrl
E: ID_USB_DRIVER=usbhid

When I use evdev:atkbd:dmi:* as the device identifier instead the change is correctly applied to my laptop keyboard so I know the rule and the process I'm using to remap the keys should be correct, it's got to be an issue with the wrong identifier (though I've quintuple checked it).

Any help will be appreciated.

Microsoft Ergonomic Keyboard the 2019 model (not the old one 4000 model) generates several keystrokes for the new keys. It is well known how to remap the Zoom slider of the old version however the question is how to do that for the new keys. The udev rules allow to specify only one scancode for a mapping entry, for example KEYBOARD_KEY_0c022d=pageup.

Here is an output of evtest for the Office key:

Event: time 1604142043.024827, type 4 (EV_MSC), code 4 (MSC_SCAN), value 700e0

Event: time 1604142043.024827, type 1 (EV_KEY), code 125 (KEY_LEFTMETA), value 1

and here for the Emoji key:

Event: time 1604142174.537667, type 4 (EV_MSC), code 4 (MSC_SCAN), value 700e0
Event: time 1604142174.537667, type 1 (EV_KEY), code 29 (KEY_LEFTCTRL), value 1
Event: time 1604142174.537667, type 4 (EV_MSC), code 4 (MSC_SCAN), value 700e1

Event: time 1604142174.537667, type 4 (EV_MSC), code 4 (MSC_SCAN), value 700e2
Event: time 1604142174.537667, type 1 (EV_KEY), code 56 (KEY_LEFTALT), value 1
Event: time 1604142174.537667, type 4 (EV_MSC), code 4 (MSC_SCAN), value 700e3
Event: time 1604142174.537667, type 1 (EV_KEY), code 125 (KEY_LEFTMETA), value 1
Event: time 1604142174.537667, -------------- SYN_REPORT ------------
Event: time 1604142174.545449, type 4 (EV_MSC), code 4 (MSC_SCAN), value 7002c
Event: time 1604142174.545449, type 1 (EV_KEY), code 57 (KEY_SPACE), value 1

So the Office key generates only the modifiers keystrokes and the Emoji key generates the modifiers keystrokes and the space keystroke after about 8 milliseconds. There are also other new custom keys on that keyboard which generate servers keystrokes, however the Office and Emoji keys are most important to remap because of their location.

I have a Microsoft Ergonomic Keyboard which I am generally enjoying. Unfortunately, it comes with a premade Office key for use in Windows in place of a right Ctrl or Super. I used xev to record what the Office key actually outputs, and it acts as a combination of the Ctrl,Shift,Meta,Super keys.

"Office" key output

Keycode | Name      | Keysym
     37 | Control_L | 0xffe3 |
     50 | Shift_L   | 0xffe1 |
     64 | Meta_L    | 0xffe7 |
    133 | Super_L   | 0xffeb |

I have looked at xmodmap, but it is deprecated in favor of setxkbmap.

Can anybody help me determine how to rebind the key combo above to act as a different modifier, like Ctrl-R or Super-R?

I am looking for an updated answer to this question and this question. After reading those two posts, I have no idea if any of the suggestions will apply to 18.04 because they're rather old. Also, while those posts request help for only certain buttons, I need help for all of the special buttons except Volume (Favorites, Calculator, navigation). The normal keys work (home, end, pgdn, pgup, number pad, etc.).

Do I need to do this? -->

Create the file /etc/udev/rules.d/98-ms-ergo.rules with the following contents:

ACTION=="remove", GOTO="keyboard_end"
KERNEL!="event*", GOTO="keyboard_end"
ENV{ID_INPUT_KEY}=="", GOTO="keyboard_end"
SUBSYSTEMS!="usb", GOTO="keyboard_end"

SUBSYSTEMS=="usb", IMPORT{builtin}="usb_id"

ENV{ID_VENDOR}=="Microsoft", ENV{ID_MODEL_ID}=="00db", RUN+="keymap $name 0xc022d pageup 0xc022e pagedown"

GOTO="keyboard_end"

Or is there something available in the repository?
Many thanks!

I use a Microsoft Natural Ergonomic Keyboard 4000 on Ubuntu 10.10. The multimedia keys (Volume, Play/Pause) work, the Mail and Calculator button as well.

Now I would love to use the zoom slider, if it were possible I'd like to use page scrolling with that. Is there some way to enable that?
