Since no one else has answered, I'll take a stab.  I have used LVM on several 
permanent hard drives, but never on removables.  However I think what your 
looking to do is a udev script.  Check out the information on udev.  Also 
look for hotplug.  

What you'll want your script to do is upon detecting the plugging of your USB 
drive, it will want to scan (vgscan/lvscan) the drive for LVM volumes, then 
activate the volume (vgchange/lvchange --available=yes).

I'm not sure what you want to do for unplugging.  I expect that you'll need a 
script to flush then deactivate the volumes prior to pulling the plug on the 
drive.

As I said, I don't know much about hotplug and udev, but this may give you 
some additional search hints.
