My S6 Active no longer works with any computers...

Was going to transfer some Roms between my phone and computer when I suddenly start receiving this notice:

"The last USB device you connected to this computer has malfunctioned and windows doesn't recognize it"

Upon further inspection in the device manager I get this:

Unknown USB Device (Device Descriptor Request Failed)

I've tried uninstalling it numerous times and have tried reinstalling the official Samsung drivers but nothing is working. It's not working on any computer I try it with so at this point I don't know what else to do. It was working fine just a few hours ago.
