I looked at every line mentioning the device in the strace log and I found this error.
Does someone now what this mean ? Or am I looking at the wrong place ?
```
stat("/dev/input/js1", {st_mode=S_IFCHR|0664, st_rdev=makedev(13, 1), ...}) = 0
openat(AT_FDCWD, "/dev/input/js1", O_RDONLY) = 31
ioctl(31, EVIOCGNAME(128), 0x7ffec665d9c0) = -1 EINVAL (Invalid argument)
close(31)   
```
