Default What is the upper USB port for on the SDS100?

The lower jack is marked "Charge", the upper micro USB port is not labeled nor discussed in the manual. So the first attempt to interface the SDS100 to my laptop, I used a micro-USB cable that I had and nothing happened, then I watched the video on ScannerMaster and it showed using the supplied USB cable and connect it to the charge USB port. So what is the upper port for?

Thanks

I believe they said it will also currently power the unit but not charge the batteries.

I did just verify that the scanner will work (but not charge) with power from the upper USB port (battery removed to test!).

Hello,

The upper port has the same USB ID as the lower one, so I connected it up to my laptop and the port got recognized as an Uniden serial port. So far I saw several SDS-100 SUB strings transmitted, but I have not tried to figure out any commands yet. I assume it is an USB port connected to the infamous sub-processor. It could be the Uniden engineers used it as a debug dump port to get it going and left most of the code in place. Some future firmware might change the usb configuration so you could plug in a device, like an USB Toaster.
