I don't, because I don't feel the need to.
According to its man page description, sync "flush file system buffers", 
but the destination is a raw device, not a filesystem, so filesystem 
buffers should not be involved.

Not in my experience when writing to the raw USB device.
The USB drives I use have an activity light. It stops blinking as soon 
as the dd or cp command terminates. I also monitor block I/O with vmstat 
and block writes drop as soon as dd or cp terminates. If I run sync, I 
do not see any more activity from the light or vmstat.
