Alright.
This unit is defective. There is one chip in the dock that cannot get the firmware to be updated. It fails authentication. This is hardware fault, this cannot be a driver fault.
Please contact Dell to request a replacement.
Do include a link to this thread for your to skip the have you tried this or this or this steps!
DisplayLink is a semiconductor company, we do not design, manufacture or sell docking stations. This is why I invite you to contact the seller, Dell, to get the hardware support you need.
In the future, if you do not wish to wait, please use technical support tickets (
explained where you found the diagnostic tool) instead of relying on forum support.
Kind regards,
