Estou tentando fazer com que um dispositivo USB HID funcione no Ubuntu, mas parece que ele não funciona. É um dispositivo USB HID e aparece como tal no dmesg:
[ 2236.277518] usb 1-1: new full-speed USB device number 17 using xhci_hcd

mas o driver genérico-oculto não está carregado e nada de novo aparece em /dev/hidraw*
A execução de lsusb no dispositivo (que é exibido em /dev/bus/usb/001/ ) fornece:

Que mais uma vez implica um dispositivo USB HID.

Eu criei uma regra do udev em /etc/udev/rules.d/99-hid.rules com o conteúdo (e variações sobre isso):
SUBSYSTEM=="usb", ATTRS{idVendor}=="0b6a", MODE="0666"
KERNEL=="hidraw*", ATTRS{busnum}=="001", ATTRS{idVendor}=="0b6a", MODE="0666"
Mas isso não parece ter feito nada (mesmo depois de recarregar com udevadm control --reload-rules e reinicialização).
Eu estou em uma perda completa sobre o que fazer aqui, outros dispositivos HID funcionam muito bem (por exemplo, desconectando e conectando meu teclado dá o seguinte no dmesg:)

Algum conselho sobre como reconhecer este dispositivo como um dispositivo HID?
Obrigado!
