I just picked up a Transformers LE (combo) and have been struggling to get the USB port to recognize any USB stick. I'm testing side-by-side with my X-Men Pro which recognizes the same USB stick immediately, so I doubt it's a formatting problem. I have tested around 6 different USB sticks, and none are recognized. Both testing using the update code function (cold reset with DIP switch 8 on) and using the code backup option from the Settings menu, but the DMD forever says to insert a USB. One of my sticks has an LED which illuminates when I plug it in, so I doubt it's a power issue.
The settings reports: V1.0, sys V1.59, HW 2
Is there any known issue with this machine recognizing USB devices, or should I suspect a damaged SAM board?
