It looks like this is the problem.  On a working installation I get the
following...

[perkinjo at head ~]$ srun -n 2 ls -l /dev/limic
crw-r--r-- 1 root root 249, 0 Feb 22 01:32 /dev/limic
crw-r--r-- 1 root root 249, 0 Feb 22 01:32 /dev/limic

It seems that the mask of device file didn't take effect and non-root
users cannot read the device.

Do you know with which options LiMIC2 was configured?  I suggest
`--enable-module --prefix=/usr --sysconfdir=/etc'.
