Hi there!


Kindly share to us the exact model of your machine and follow the troubleshooting steps below to further isolate the problem.

Could you try the below mentioned steps?


  • Go to control panel, Open Device Manager.
  • Scroll down to the bottom of the Device Manager Window, and click on “Universal Serial Bus Controllers” to expand it.
  • Right-click on the first entry in the expanded list named “USB Root Hub,” and select Disable from the context menu.
  • Right-click once again on that same “USB Root Hub” entry, and select Enable from the context menu.
  • If it works, the list of items under “Universal Serial Bus controllers” should refresh, and you should see some additional items in the list. 
  • The USB ports on the docking station and devices connected to them should be working once again.
