Thanks!
I will do some research on MTP later on.

 I have a Samsung Galaxy Indulge (R910, Android
 2.2.1) phone that 
 automagically mounts on
 Wheezy Xfce when plugged in.  Then metroPCS 
 upgraded their cellular network, dropped
 support for that model, and I 
 needed a new
 phone.
 
 
 So,
 I bought a Motorola Moto G (XT1045, Android 4.4.4) from
 AT&T.  When 
 I plugged it in to Wheezy
 Xfce, nothing happened.  After much STFW, 
 RTFM, etc., I learned that I needed to use
 Media Transfer Protocol:
 
  
    https://en.wikipedia.org/wiki/Media_Transfer_Protocol
 
 
 This is
 available via FUSE on Wheezy.  I installed two Apt
 packages:
 
  
    jmtpfs
  
    mtp-tools
 
 created a mount directory:
 
      $HOME/xt1045
 
 added myself to the FUSE
 group:
 
  
    usermod -a -G fuse dpchrist
 
 and figured out how to mount
 and umount the phone.  (I can't remember if 
 I needed to do anything on the phone, and I
 don't see anything in the 
 settings now
 that looks relevant.)  I put the relevant commands (with
 
 some simple checks) into a pair of shell
 scripts.  See the sample 
 console session
 that follows.
