I have a Dell G7 laptop, UD-3900 docking station. With the USB keyboard connected to the docking station, I have a pretty frequent issue with the keyboard lagging out for a few seconds and then repeating the last letter I typed four or five times. Plugging the USB keyboard into the laptop directly resolves the issue. I’m using the latest DisplayLink drivers (installed last week) and it’s a new keyboard.
I saw a thread from May, Sporadic keyboard lag/repeating characters with UD 6950, with the same issue. The link to a driver/patch from Dell in there is not working.
Any ideas welcome.
