Mine use uno’s and mega’s.

If you look at most arduino’s, between the USB and the power regulator is a tiny 3 pin chip.

All removing it does is cut power between the USB and the rest of the device. It still powers from the vin pin and the circular power connector, etc. it just no longer will pull power from the USB.

Now…. Before you do this, you can tell if it will help you. If you power the device from the vin pin or the circular connector, that diode won’t conduct and it shouldn’t pull power from USB and your computer shouldn’t crash. If powering one still shows crashes, power both externally, and if it still crashes, then this won’t fix it.

That said, here’s a picture of the chip in question. The tweezer points to it.
