OK: it's compiled into kernel and not as a module.
If things _still_ don't work after stuff below, then an option may be to
compile
as a module: but I think we'd not need to go that route.

Just to check: you _do_ have an /etc/nsswitch.conf file, yes (the grep
above doesn't complain about it being missing)?
Can you, just for ref and dbl-chk, post the current /etc/nsswitch.conf contents
-
omit commented-out stuff and blank lines.
Can you add the following near to the end of the file - e.g. just above the
'aliases: files' line:
automount: files
It doesn't matter whether you use a tab or spaces in the line.
It's not always strictly necessary to have this entry in nsswitch.conf: but at
least for debugging, it helps nail-down where info is being looked for by
automount.

Can you stop/kill the currently-running automount process, and verify via ps or
similar that there's no automount processes running, and then run automount
manually and in debug mode at console via:
$ automount -v -f -d
$
'-v'==verbose,
'-f'=='foreground & log to stderr instead of syslog',
'-d'=='debug-level of info'.
You might want to omit the '-d' at first in case it gives too much info.
Just use ctrl-c when you want to quit out of it.
Without the above-noted addition to /etc/nsswitch.conf , you should see
automount
complain about 'syntax error in nsswitch config near [ syntax error ]' .
Can you post the output of a run without the '-d', and then with the '-d', that
shows what happens when you plug in the usbstick.

Have left the above chunk of notes in-place in case we need to go onto that.
