There has been alot of confusion about the Original #11 and #18 cameras so heres the story behind it.

The vendors came out with a newer camera and called it the #18.
Chuck lohr (808 camera guy) said it was not a new model but an updated #11.
So the name changed to UPDATED #11. Being alot of people already associated
the updated camera as the #18 the vendors continued using the name,sometimes
even calling it the original/updated/#11 camera when its really a #18.

The updated #11 or the #18 uses a smaller 8 pin USB and the bottom of case embossed with a #18 and serial numbers.

The original #11 used a standard 5 pin USB and the bottom was not embossed.

The original/updated/#18 can all use the same firmware.
