Nope, no dice... If the serial is powered you get the summary of the SD contents, then when you plug-in the USB you get "USB connected" and the little train of dots, but the same error occurs; the MSD device is recognized, but no drive is mounted.
Not sure where to go from here; there has to be something up with the code, or the manner in which it is being executed... :( Thanks.
