Happy pedals XPL issue
- X-Plane od 10.10 nepoužívá linuxové rozhraní /dev/input/jsX.
- protože js rozhraní omezuje: podléhá kalibraci, zavádí například null zóny atd…
- Místo toho /dev/input/eventX
- vyžaduje oprávnění na eventX
- stačí chmod o+r
- machři to dělají přes udev rule
- eventX lze identifikovat podle id nebo path, podle id takto:
Pharaon:/dev/input/by-id# ls -la /dev/input/by-id/ celkem 0 drwxr-xr-x 2 root root 240 zář 3 21:04 . drw-rw-r-x 4 root root 320 zář 3 20:49 .. lrwxrwxrwx 1 root root 9 zář 3 20:49 usb-Arduino_LLC_Arduino_Leonardo-event-if02 -> ../event7 lrwxrwxrwx 1 root root 9 zář 3 19:47 usb-Logitech_Gaming_Mouse_G300-event-mouse -> ../event2 lrwxrwxrwx 1 root root 9 zář 3 19:47 usb-Logitech_Gaming_Mouse_G300-if01-event-kbd -> ../event3 lrwxrwxrwx 1 root root 9 zář 3 19:47 usb-Logitech_Gaming_Mouse_G300-mouse -> ../mouse0 lrwxrwxrwx 1 root root 9 zář 3 19:47 usb-Logitech_Logitech_Extreme_3D-event-joystick -> ../event6 lrwxrwxrwx 1 root root 6 zář 3 19:47 usb-Logitech_Logitech_Extreme_3D-joystick -> ../js0 lrwxrwxrwx 1 root root 9 zář 3 19:47 usb-Logitech_USB_Keyboard-event-if01 -> ../event5 lrwxrwxrwx 1 root root 9 zář 3 19:47 usb-Logitech_USB_Keyboard-event-kbd -> ../event4

- oprávnění určitě měl!!
- dostal file deskriptor number
- a testoval jsem to i přes grep -i permission
- a navíc jsem to omylem spustil pod rootem :)
- a takhle X-Plane pozná, zda je tam nový device
