Strange. In both the current Flex I am driving and my previous Taurus X, I could have a flash drive (or Creative Zen MP3 player) connected to USB and another device to USB2 simultaneously and switch between them at will and both function perfectly fine. Is your Sync system at the latest software level per SMR.com? My Taurus X was at 1.2 and the Flex is v2.0.

I don't think that the open USB port is used at all, either by the factory or anyone else. When the dealer has to update the module, they do so through the same USB port you use. I'd bet the modules come to the factory pre-programmed. I'd suspect the open port is there for future expandability. Which kind of worries me when I realize that without a properly latching connector (like the factory one in the primary port), there's a good possibility that the cable and connector are vibration/shaking/moving as I drive down the road. That can't be good for the circuit board...

Oh, here's a pic of USB2 working on my Taurus X. FYI- I've had this working since September, but never thought to post anything about it anywhere.

I assume you're "SoCal Edge" on the SMR forums. Here's a photo to show that USB2 does in fact work (if my attachment works). As you can see, it is playing one of my favorite podcasts via USB2. I added this to my Flex today. I previously had the same cable on my last vehicle, which got left at the dealer last week when I picked up my Flex. EDIT: The Sync module (APIM) on every vehicle has a spot for a second USB port. Once you plug something in, it will work. You just have to find the Sync module and the right USB cable/adapters. I used an extra cable and got a $4 adapter. Voila, 2nd port. Very low effort with a high return.
