Ma règle personnalisée udev hwdb ne fonctionne pas

Question

J'utilise ubuntu 14.04 installé en mode EFI, j'ai essayé d'écrire une simple règle udev qui, pour tous les claviers USB externes, mappera capslock pour échapper. J'utilise beaucoup de vim et branchez et débranchez souvent les claviers, ce qui simplifiera beaucoup les choses. Donc, après différents tutoriels, j'ai créé un tel fichier

cat /etc/udev/hwdb.d/61-keyboard-local.hwdb keyboard:usb:v*p* keyboard:usb:v046dpc30e* KEYBOARD_KEY_58=esc

alors j'ai exécuté

udevadm hwdb --update

mais ça ne marche pas. J'ai utilisé la première règle générale de mappage doublé pour n'importe quel clavier USB

keyboard:usb:v*p*

et pour celui que j'avais déjà branché

keyboard:usb:v046dpc30e*

je pensais que des travaux spécifiques fonctionneraient, mais malheureusement pas.

alors j'ai essayé de déboguer ce qui ne va pas et après un autre tutoriel, lancez ceci:

udevadm --debug test /devices/pci0000:00/0000:00:14.0/usb3/3-2/3-2:1.0/0003:046D:C30E.0007/input/input20 calling: test version 204 This program is for debugging only, it does not run any program specified by a RUN key.

Une idée de comment je peux le déboguer et le faire fonctionner?

megahallon · Answer

Le format est KEYBOARD_KEY_<hex scan code>. Utilisez "evtest" pour trouver le code de numérisation correct. Exécutez-le, sélectionnez le périphérique approprié et appuyez sur la touche pour laquelle vous souhaitez utiliser le code de balayage. Cherchez quelque chose comme:

Event: time 1410505361.975680, type 4 (EV_MSC), code 4 (MSC_SCAN), value 70039 Event: time 1410505361.975680, type 1 (EV_KEY), code 58 (KEY_CAPSLOCK), value 1

Vous voulez que le code soit situé après MSC_SCAN, alors sur mon clavier, il est 70039, je pense que cela est vrai pour tous les claviers USB.

Aussi, après:

udevadm hwdb --update

vous avez besoin:

udevadm trigger

Pour activer le nouveau mappage.

J'avais un problème similaire. Pour moi le problème est en fait ici:

kmod load $env{MODALIAS}' /lib/udev/rules.d/80-drivers.rules:5

Je suppose que ce que vous voulez, c'est une autre règle, mais vous obtenez ceci:

kmod load input:b0003v046DpC30Ee0110-e0,1,4,11,14,k71,72,73,74,75,77,79,7A,7B,7C,7D,7E,7F,80,81,82,83,84,85,86,87,88,89,8A,B7,B8,B9,BA,BB,BC,BD,BE,BF,C0,C1,C2,F0,ram4,l0,1,2,sfw

Essayez de rajouter:

DRIVER!="?*", ENV{MODALIAS}=="?*", RUN{builtin}="kmod load $env{MODALIAS}"

Vers la ligne 5 de 80-drivers.rules et voyez ce que vous obtenez.
