I recently purchased a UGA-3000 USB video adapter. I am using it to provide a second monitor with a MS Surface Pro 3, Windows 10 Pro, MS docking station.
I get terrible mouse and keyboard lag at unpredictable intervals. Mouse and KB are both wireless Logitech which communicate via a single USB dongle.
The only common thread I have been able to find so far is that when the lag occurs, I can get rid of the lag by disconnecting the UGA-3000 from the docking station and removing it from devices.
Later, I can reconnect it and have a second monitor for a while, but the lag always returns, and it’s intolerable.
Hi Russ, thanks for posting. Sorry to hear of the lag you are experiencing while our adapter is connected and I will be happy to help!
Thank you for the description of the behavior. Based off of your description, it sounds like you may be experiencing a wireless interference issue that can occur between any USB 3.0 device (not just our adapter) and the 2.4GHz wireless signal from the wireless receiver for keyboards and mice. Although a bit technical, Intel has written a paper of the behavior –> http://www.intel.com/content/www/us/e… When you connect the adapter to the USB 2.0 port, this will not happen as the electrical signal is not moving in a manner to create this interference; however, this would not be a viable test as the MS dock (assuming you are using this one –> https://www.microsoftstore.com/store/…) and Surface Pro 3 only have USB 3.0 ports.
Assuming that you have our adapter and the Logitech wireless USB receiver connected to one of the USB ports on the Surface Dock, would you be able to temporarily test moving the USB receiver to the USB port directly on your Surface Pro 3 in order to see if the interference continues?
If this test does not yield better results, there may not be much else we can suggest to resolve the lag. But I would be happy to examine some log files from the system to see if there is any other variable that can be checked that could attribute to the lag. To help me do so please download and run our diagnostic utility PlugDebug –> http://plugable.com/support/plugdebug with everything connected. Please send us the file that is created on your Desktop by attaching it to an email to our direct support email address at support@plugable.com with ‘Ticket Number 161632’ in the subject line so we can match everything up. We’ll then examine the logs and go from there.
So far, I have experienced lag with the UGA-3000 in both of the 3.0 ports, but I have NOT YET connected it to either of the 2.0 ports, because for some reason I thought the UGA-3000 required 3.0.
I just now connected the UGA-3000 to one of the USB 2.0 ports on the docking station, and it is working. I will test it like that this afternoon and evening. After that I will be unable to run any more tests on the docking station for a while.
