Ender 3 SKR mini E3 v2 not connecting

I recently installed an SKR mini mainboard into my ender 3 and everything runs fine. I went to set up Octoprint on my raspberry pi 4. But I cannot get the Pi to see the mainboard. I have tried multiple different cables and tried snipping the positive line in each one that I have tested. Does the mainboard need special firmware or is my mainboard's USB port dead?
