I confirmed that the USB port does provide power to the arduino but the desktop can't  find the  board.
It's an uno. Is there a way to fix it? Just for fun where do I check for shorts?


Have you tried another usb lead?
It is possible for a cable to go bad.  If only a data wire broke you would still get power.

I definitely killed the connection.  I tried different cables and computers. They see a working uno I have fine.
Just wondering if it's fixable by replacing some component.

It still works but can't upload new  code.

What component?

Do you get a sync error?
If yes, is your board installed and visible through device manager ? Is IDE configured correctly?

Perform the loop back sketch test, that will determine if it's a serial USB problem or a bad 328 problem.

Device can't be found in the device manager or terminal. So it is a usb problem.
My computer can see my other working boards. I guess it goes in the trash. I can salvage the 328.
