Hi
I am using Arduino nano Chines clone and it is working but only issue is whine external power is connected ( Vin) can't program ( upload ). Once the External power is removed I need to remove the USB cable and re connect then I can upload without fail.
Please advice and modification to be done or reason to this issue
Thanks in advance

Talk to your chinese clone supplier - this is not an Arduino issue.
Dear spycatcher2k
I am 100% agreed with you. Could you please advice what kind of engineering solution that we can apply to solve the issue
Sure - provide a full schematic, and I'll have a look at it.
