Some of the event devices (unfortunately not all, and probably not those that you want

) also have symbolic names:
Code:
[root@kindle input]# ls -la
drwxr-xr-x 3 root root 160 Mar 10 18:15 .
drwxr-xr-x 16 root root 1120 Mar 11 15:15 ..
drwxr-xr-x 2 root root 100 Mar 10 18:15 by-path
crw-r----- 1 root root 13, 64 Mar 10 18:15 event0
crw-r----- 1 root root 13, 65 Mar 10 18:15 event1
crw-r----- 1 root root 13, 66 Mar 10 18:15 event2
crw-r----- 1 root root 13, 67 Mar 10 18:15 event3
crw-r----- 1 root root 13, 68 Mar 10 18:15 event4
[root@kindle input]# ls -la by-path/
drwxr-xr-x 2 root root 100 Mar 10 18:15 .
drwxr-xr-x 3 root root 160 Mar 10 18:15 ..
lrwxrwxrwx 1 root root 9 Mar 10 18:15 platform-soc-audio.1-event -> ../event1
lrwxrwxrwx 1 root root 9 Mar 10 18:15 platform-whitney-button-event -> ../event2
lrwxrwxrwx 1 root root 9 Mar 10 18:15 platform-zforce.0-event -> ../event4
Still, that would mean only figuring out what the remaining two are, instead of guessing what all 5 are.
