Please set mgnokiidev to setuid root.

It's ok.

It seems the error lies somewhere in mgnokiidev, the relevant strace
output:

    access("/mnt/card/usr/sbin/mgnokiidev", X_OK) = 0
    socketpair(PF_UNIX, SOCK_STREAM, 0, [5, 6]) = 0
    fork(Couldn't open pty!
    )                                  = 657
    --- SIGCHLD (Child exited) ---
    close(6)                                = 0
    wait4(657, [WIFSIGNALED(s) && WTERMSIG(s) == SIGSEGV], 0, NULL) = 657
    write(2, "wait: : No such process\n", 24wait: : No such process
    ) = 24
    recvmsg(5, {msg_name(0)=NULL, msg_iov(1)=[{"@", 1}], msg_controllen=0, 
msg_flags=0}, 0) = 0
    close(5)

It seems mgnokiidev got a segfault. Please create another strace
output which trace the child process too (add the -f flag).

Bye,
