raspberry pi repair – no usb with over-current change error message

At $DAYJOB, I’ve set up a number of raspberry pi kiosks out in our shops to display drawings and other info to our shop employees. I’ve recently ran into an issue on a few of our units where the usb ports stop working and the error logs fill with this message:

[ 133.401276] usb 1-1-port2: over-current change

In researching the error, I came across this thread on the raspberry pi forums.

In short, the problem can be fixed by removing C97, then disconnecting pin 3 from U13, then shorting pin 1 to pin 6 of U13. This disables the current limiting for the usb ports keeping the pi from disabling them.
