Ribbon cable connected to USB

Hi everyone,

Made a big mistake a while ago and I cant use my pitop since. The Little black ribbon cable starting from the two USB (the one plugging into the raspberry Pi) and goin under the SBC and connecting to the rest of the pitop, it is broke and I have reached for help to the support 9 month ago but never had an answer. Im looking now to bring the pi top alive and would greatly appreciate some help. I assume the part come with the two USB port integrated so it is tricky to find.

Please help
