aqui a solução: link
existem 2 tipos de adaptadores: o primeiro simplesmente troca um plug por outro, o outro trabalha com sinais.
Tenho um teclado ergonômico antigo e adorável (sem nome SK-6000) conectado por meio de um adaptador DIN- > ps / 2 a um adaptador ps / 2- > usb à minha estação de acoplamento. Depois do Grub ele pára de funcionar. É preciso suspendê-lo e reativá-lo enquanto o Linux está em execução para que ele funcione. Nenhum módulo extra do kernel é carregado para isso. Quando ele funciona e eu reinicio sem desligar, ele funcionará imediatamente.
Mesmo quando não funciona, é visível (o número do dispositivo lsusb varia, mas a saída é idêntica, esteja funcionando ou não):

Ao fazer a replicação, o dmesg mostra isso (que, exceto pela primeira linha e diferentes números de entrada já vieram no momento da inicialização):

Então eu tentei

As linhas posteriores soam como se já estivessem lá. E nada disso acorda o teclado:
$ sudo udevadm trigger --verbose --sysname-match=usb*

$ sudo udevadm trigger
Eu também tentei isso sem sucesso:
# 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
O que mais devo tentar obter o mesmo resultado de replicação ou suspensão, apenas emitindo um comando?

Eu também estava enfrentando o mesmo problema.
Solução (não tenho certeza sobre a causa raiz, mas isso funcionou para mim):
