user4843: I have a Uno (third party) that I connect to my Dell laptop with no problems at all. But I've just received a Nano (also third party) that I just can't get to upload. After lots of interneting, I hit Windows normally-useless troubleshooting tool. That tells me that the USB device (the Nano) doesn't understand USB3 and I should plug it into a USB2 port. Unfortunately, being a new machine there IS no USB2 port.
Is Windows Troubleshooting lying? Is there a problem interfacing with a Nano via USB3?
Edit: Error message is:
stk500_recv(): programmer is not responding


user26183: I have run in to similar symptoms while using USB based Arduino clones connected to USB3 ports. Connecting them to a USB2 port on the same PC worked (where this was an option).
For computers that only have USB3 ports, I found that connecting the device via a cheap USB 2.0 hub (not USB3 hub) solved the issue.
I'm not sure why these devices behave like this, but there seems to be something about USB3 ports that these boards don't like.
