Dear friend,
Could you please uninstall the driver first, and then follow the steps:

3. Plug DUE again, let it installed automatically.

After finish tested, please tell me the results.
Waiting your reply. Best regards.

that link had a bunch of links that it tried to trick me into installing malware with huge "DOWLOAD NOW" buttons and fake "Download" buttons...I found the correct link eventually, but the page seems kind of strange.

Dear friend,
Could you please download Driver Genius?
This is the link:

Best regards.

that site is not in english.

the USB works fine when the FD power is off, and stops working when the power is on. This hardly seems like a driver issue.

Dear friend,
You can pull out jumper caps on VIN, and then use USB supply power.
Best regards.

with the vin jumper out, it acts the same as in my original post.

Dear friend,
Could you please use USB to connect DUE and computer?
Please note that don't connect to FD and other peripheral device module.
Waiting your reply.
Best regards.

Yes. I have it connected to the usb.

Dear friend,
Could you please tell me whether you can find com port or not when you connect DUE and Computer?
If not, maybe there has problem on 16u2. You can use usbtiny to upload bootloarder.
If you can find com port, the mcu probably has problem.
Waiting your reply. Best regards.

The Due communication works fine, unless the FD is connect with the power on AND the jumper as described.
