    There is no benefit in turning off the USB dipswitch if your board will be deployed with only a Lipo for power.  The switch is there solely for the purpose of deactivating the USB interface chip in case you are powering the Mayfly via the USB jack and want to save power, because the CP2102 chip can draw up to 10ma when idle, so turning it off can be useful.
