Ho una bella tastiera ergonomica antica (senza nome SK-6000) collegata tramite un adattatore DIN- & gt; ps / 2 ad un adattatore ps / 2- & gt; usb alla mia docking station. Dopo Grub smette di funzionare. Ci vuole per sospendere e svegliarsi o per ripristinarlo mentre Linux è in esecuzione per farlo funzionare. Nessun modulo del kernel aggiuntivo viene caricato per questo. Quando funziona e ricomincio senza spegnere, funzionerà immediatamente.
Anche quando lo fa non funziona, è visibile (il numero di dispositivo lsusb varia ma l'uscita è identica sia che funzioni o meno):

Ho anche provato questo senza alcun risultato:
# echo -n 0003:0A81:0205.0001 > /sys/bus/hid/drivers/generic-usb/bind
ksh: echo: write to 1 failed [No such device]
# echo -n 0003:0A81:0205.0001 > /sys/bus/hid/drivers/generic-usb/unbind
# echo -n 0003:0A81:0205.0001 > /sys/bus/hid/drivers/generic-usb/bind
# echo usb1 >/sys/bus/usb/drivers/usb/unbind
# echo usb1 >/sys/bus/usb/drivers/usb/bind
Che altro dovrei provare a ottenere lo stesso risultato di replugging o suspending, semplicemente emettendo un comando?
È necessario inviare questa domanda a serverfault.com
Probabilmente no, ma una cosa che potresti controllare è la corrente nominale di corrente dell'adattatore PS / 2. Puoi vederlo correndo

lsusb -v e cercando "MaxPower" del dispositivo appropriato. Penso che la corrente massima per PS / 2 dovrebbe essere 275 mA. L'USB può essere da 0 a 500 mA, a seconda della configurazione richiesta dall'adattatore. Oh, e un'altra cosa che potresti provare è inserirla in un hub autoalimentato e vedere se si riproduce.
solo per completezza lo stesso - la vecchia spina grassa si chiama DIN9. Non ne ho visto uno dal mio vecchio xt tho; p

Oh, non è colpa di Linux. È molto probabile che la configurazione maledetta sia così complicata. I VAGUELY sembra pensare che le tensioni di avvio siano in difetto qui, ma questo è solo un istinto infondato.
