I'm not quite sure what led to this issue, but 1 of my USB ports suddenly stopped working. Here are some of the details:

It seems that the USB at Bus 001 Device 001 is using a module for USB-3 types instead of for USB 2(ohci_hcd). I'm thinking that pointing it from xhci_hcd to ohci_hcd will fix the issue but I'm not sure and I don't know how to force it to use the correct kernel module. I tried sudo modprobe -r ohci_hcd and sudo modprobe ohci_hcd, then reboot but it did not work.
This issue makes the USB port unusable and does not return any result(sudo tail -f /var/log/messages) when I try to plugin different USB devices. Please help.
