Integration USBRelay8 in to linuxcnc

[pklepko]

hello, I am trying integrate USBRelay9 in to linuxcnc.
There is HAL module named "hal_input" that is able integrate any HID device that is listed in /proc/bus/input/devices.
When I plug this USBRelay8 in computer it is shown as /dev/hidraw2 , I can use utility "usbrelay" .
Device is also not listed in /dev/input
But device is not listed /proc/bus/input/devices.
To be listed there it should be declared as HID device driving LEDs like CapsLock, or Numlock leds in classic keyboard.

Is it possible create specific udev rule for this device that there will be loaded udev handler "leds" ?

I too use linuxcnc. I have recently been playing with hal_input. I don't think it will do what you want. I haven't tried this but you can call a shell script (which calls usbrelay) from MDI in linuxcnc. I haven't tried it, but this forum post might give you some hints.
