LIFEBOOK E754 docking station usb ports not working

[thahgr]

Hello,

I have the LIFEBOOK E754 its docking station. From one day to another, the usb ports of the docking station have stopped identifying the devices connected to. Power is reaching the devices, i.e. mouse light is on but mouse is not working.
The same happens with all devices, the get powered but not identified.
This does not happen at the laptop's usb ports. Only at the docking station.

Thank you for your help
