Hi there and welcome
The USB ports are hardwired into the Mainboard, there is no way to alter them. But it looks like these are damaged as well, functioning but still damaged, if they're not booting up when memory sticks run or if they're experiencing multiple collisions on the data transfer which results in slowing it down (you cannot just speed up the ports).
One thing you can try is to use a powered USB hub and plug this into the USB port, which then takes the power requirement away from the port so it only has to focus on data transfer as opposed to also supplying power.
Do you have a USB hub with its own power available there?
