EPERM (Operation not permitted) while trying to open Acer BMA150 accelerometer

[sm4rk0]

I'm running hdapsd on ubuntu 17.04, version 1:20141203-1.

sudo strace hdapsd
shows this error:

open("/dev/input/event8", O_RDONLY) = -1 EPERM (Operation not permitted)

cat /proc/bus/input/devices

I: Bus=0019 Vendor=0000 Product=0000 Version=0000
N: Name="Acer BMA150 accelerometer"
P: Phys=wmi/input1
S: Sysfs=/devices/virtual/input/input11
U: Uniq=
H: Handlers=event8 js0
B: PROP=0
B: EV=9
B: ABS=7

Tried sudo rmmod joydev but nothing changed except no "js0" in Handlers list
Any idea?
