usbhub and usbd are the usb root hub drivers, usbehci and usbport are used to communicate over the pci bus and peauth I'm not sure. All the usb***.sys drivers should be from Microsoft and should all be signed. I would try copying those drivers from another system, uninstall and copy then new drivers into C:\Windows\System32\drivers then select scan for hardware changes. Hopefully it should load the signed drivers.
