J'ai un beau clavier ergonomique ancien (sans nom SK-6000) connecté via un adaptateur DIN-> ps / 2 à un adaptateur ps / 2-> usb de ma station d'accueil. Après Grub, il cesse de fonctionner. Pour que cela fonctionne, il faut soit suspendre et réveiller, soit le rebrancher pendant le fonctionnement de Linux. Aucun module de noyau supplémentaire n'est chargé pour cela. Quand cela fonctionne et que je redémarre sans éteindre, cela fonctionnera immédiatement.
Même s'il ne fonctionne pas , il est visible (le numéro de périphérique de lsusb varie, mais le résultat est identique, qu'il fonctionne ou non):

Les dernières lignes sonnent comme si elles étaient déjà là. Et aucun de ceux-ci ne réveille le clavier:

J'ai aussi essayé en vain:

ksh: echo: write to 1 failed [No such device]

# echo usb1 >/sys/bus/usb/drivers/usb/unbind
# echo usb1 >/sys/bus/usb/drivers/usb/bind
Quoi d'autre devrais-je essayer d'obtenir le même résultat que de rebrancher ou de suspendre, en émettant simplement une commande?
lsusb -v
et en recherchant "MaxPower" du périphérique approprié. Je pense que le courant maximum pour PS / 2 est supposé être de 275 mA. L'USB peut être compris entre 0 et 500 mA, en fonction de la configuration demandée par l'adaptateur. Oh, et vous pourriez également essayer de le brancher sur un concentrateur autonome et de voir s’il se reproduit.
