Is it a clone? Have you recently upgraded the drivers or software?

Many of the serial numbers used by clones have been blacklisted by Segger.

Is this related to what you ask https://www.edaboard.com/threads/296630/ ? (which means: are you sure it is the debugger fault?)

Also is this thread discussing he same problem as https://www.edaboard.com/threads/296613/ , if so why do you have users replying is two similar threads simultaneously ?

I am not trying to revive old post, I just wanted to post some additional info for future googlers on my successful experience with this procedure.

If you follow steps 1 - 11 and plug in the USB cable and still get a USB device not recognized message from windows, repeat again but try the erase steps 1-3 a few times then on step 8 wait only 10s. Atmel docs say that the tst pin need only be held high for 10s then you can disconnect and pull the jumper and plug straight back in. I did this on windows 8 and after it took, I simply plugged it in and windows did the normal looking for driver thing.

When you start the sam-ba tool, be sure to run it as administrator or else you will get weird error messages and it will crash.
