My UD3900 has worked flawlessly for over a year now. I recently applied some Windows Updates and Dell Updates (for XPS 9570 laptop) and my wireless trackpad is now operating strangely in that the Setpoint (which controls the customized settings) is disabling periodically and I have to disconnect and reconnect the UD3900 USB cable to the laptop to get it to work. I’m an IT SysAdmin Professional so usually pretty good at troubleshooting this kind of stuff but I’m at a loss at this point. I’ve also noticed at times some brief erratic behavior with the wireless keyboard that are indicative of the USB connection being briefly interrupted (behaves like a stuck key for a second.) Both bluetooth dongles are plugged into the UD3900. The Windows update was a major one updating from Windows 1903 to the 1909 version. It’s going to take many hours to try to isolate if it’s one of the Windows/Dell updates and which one so was hoping maybe some other users have run into this and can offer some suggestions? Dealing with Microsoft 1st tier support is almost always a big waste of time.
