Использование HID-совместимого мышиного устройства в Ubuntu

Цель: у меня есть доска, которая подражает мыши. Таким образом, когда вы нажимаете и перетаскиваете доску, она должна перемещать курсор. Я хочу, чтобы доска работала в Ubuntu. Она работает на Windows. Информация об устройстве: вывод cat /proc/bus/inputкоторого содержит информацию об устройстве

Поскольку bInterfaceProtocolNone, linux не распознает его как устройство ввода мыши.

Какой идеальный подход для обратного инжиниринга из окон, чтобы он работал в Linux.

Устройство в диспетчере устройств Windows:
