Hello tnsoom,
Thanks for posting your concern here.
First of all, how did you update your Surface Dock? If you updated via Windows update, we suggest to update your dock manually here: Surface Tools for IT and then download and install Surface_Dock_FwUpdate_1.53.139_Win10_17763_20.075.41193_0_AMD64.msi.
If issue persists, disable and enable USB port in UEFI**.**See How to get to the UEFI settings on a Surface for more details. Once you're in UEFI, go to **Devices,**disable Docking USB portfor at least 15 seconds and then back to enable. Click Exit and Restart device.
Hope this helps. Otherwise, don't hesitate to respond to this thread if there’s anything else that needs to be addressed.
Regards,
StevenK
