Hello, I am having an uploading problem only with my new Laptop. I have tried Windows support and two local repair shops. Can't get help anywhere. So, I hope the someone here might be able to help by looking at the Avrdude error.
My USBs work with flash drives. However, they won't work with an Arduino board or an external drive. I've tested these on other machines and they work fine.
The message I get is:
An error occurred while uploading the sketch

avrdude done. Thank you.
Problem uploading to board. See Upload – Arduino Help Center for suggestions.
I tried the link here but really can't make sense of it. Any help would be greatly appreciated
