Hi tjfdownsouth,
Sorry for the troubles you're experiencing. Lots of great advice here, and it looks like we're making progress towards getting your board re-flashed. Let's see if we can get you the rest of the way really quick.Ok I finally found the driver and it will now show up in the stdfu software. I did the steps to flash the firmware but after the demonstration program completes and I unplug and reconnect the board both lights stay on and it doesn't show in device manager.
First: please unplug any components which might be attached to your Netduino 2. We want to eliminate any possibility that too much power is being drawn during re-flashing operations. This isn't strictly necessary, but it's a good idea if you're running into troubles.
Second: in DFUSE, there is an "upload" and a "download" button. The text on them feels backwards, so it's pretty easy to accidentally overwrite your firmware .DFU file with the empty contents of your board...instead of flashing the .DFU file to your board
Third: knowing all of the above, please delete the .DFU file off of your PC and re-download it from the 4.2.2.2 firmware post; we keep the latest firmware as a sticky at the top of this forum. Then go through the re-flashing process again, paying close attention to the buttons pressed in each step. Be sure to check the box to verify that the firmware was written correctly.
Fourth: If you can take a screenshot of the DFUSE Demonstrator program (press print screen, paste into Microsoft Paint, save as JPG, and then attach to your post), that screenshot will give us a ton of information about what happened during the reflashing process.
Does that get you back up and running? Please let us know if you have any other troubles.
