New UNO, Windows7Pro avrdude: stk500_recv(): programmer is not responding

fab85:
Hi! Sorry for my late response. I'm not sure about what you mean by autoreset. I don't think I can return it since the vendor (lex...nic) doesn't respond.

The auto-reset circuit makes it so you do not have to use the reset button when uploading sketches. You did not say whether or not you actually tried to short the Reset-EN pad while trying to upload a sketch.

A quick check with a DMM would also tell you if the pad is open.
