Topic: Arduino DUE : No device found on COM  (Read 776 times) previous topic - next topic


Hi all,

When trying to upload a sketch, even "null" via the USB Programming Port of my Arduino DUE, via IDE 1.6.8,
the following error message appears:
No device found on COM (COM3 in my case)
The RX lights about 1 second before the message is delivered.

I has worked till this week-end, but now, no possibility found to make the upload.
I tried some erase / reset sequences but no results.
I tried it on 3 computers, on Vista, Windows 7 and Windows 8 with same results.
Also tried with mode com3:1200 ... Add change the USB wire...

Ideas of what happens ? And how to work ?

Thanks for tour help
