I've been working with ev3-dev for the past weeks and successfully configured various sensors and actuators. However I can't get the Actuonix Linear Actuator working.

When I try to initialize the class, it says the motor is not connected.

I checked for the driver and it is there:

robot@ev3dev:~$ cat /sys/bus/lego/drivers/ev3-motor/driver_names 
lego-nxt-motor lego-ev3-l-motor lego-ev3-m-motor act-l12-ev3-50 act-l12-ev3-100

I have changed the port and the cable just in case and had no luck.

When I create a simple Motor class in that port It uses the lego-ev3-l-motor driver.
Using that it responds to the on(vel) command, going both ways and stopping on the edges. I can't use stop() (it does nothing) and when asked for position it says 0 or 1 being fully retracted or fully extended.

Really hope for some help! Thanks
