исходники выложу на гитхаб на днях. но там мутенеько все на данный момент, торопился
у меня три интерфейса: стандартная клавиатура (boot keyboard), мышь с колесом и некая солянка из разных элементов. клавиатура и мышь (эмулируемая джойстиком и энкодером) - для системы. третий интерфейс для hal_input - определенные там юсаджи мапятся на хал пины. один из светодиодов деграется из hal, чтобы сообщить контроллеру что работает linuxcnc. в этом режиме контроллер перестает слать события о функциональных клвишах, мыши и энкодере через первые два интерфейса, а шлет их через третий.
сомнительное решение, на самом деле. мне почему-то непременно хотелось использовать input subsystem и hal_input... надо, наверное, не изгалаться и просто сделать третий интерфейс custom hid и свой hal модуль к нему. в котором все пины нормально обозвать.
