Two things I can think of to check, that caused me headaches:

1.  It seems autofs is very picky about the type of white space used to 
separate the fields.  It wants tabs, not spaces.

2.  The USB drives may actually be ending up somewhere else.  That is to 
say, maybe you got sdb the first time, when you checked with dmsg, but 
got sda or sdc the next time you plugged the USB device, because there 
was something else found before it.  I solved this by setting up to use 
label based mounting.

Add a unique label to your USB drive file system (mlabel, e2label, ...), 
for example USBDRV.  Set up auto.removable to look like this:

  usbdrive  -fstype=vfat,rw,gid=100,umask=002 :/dev/disk/by-label/USBDRV

The label, USBDRV is a link to the actual device node, as assigned by 
the system.
