        I have having a weird problem.   I have a Logitech G910 keyboard, which is a very responsive keyboard with mechanical switches.  Recently, I started having an issue where the keyboard becomes non-responsive for a relatively long time, 1-2 minutes I would estimate.  I will start to type something, or even try to select multiple objects by holding down the Cntl key, and nothing happens.  I just keep pushing keys for more than a minute, and it eventually starts working again.

        I am using it with a Dell 7510 Precision Laptop running Windows 10 2004.  I did make a change recently in the connection.  I have a large USB hub that connects the keyboard, mouse, and about 6 other USB devices.  This hub previously was connected to a USB port on the laptop.  Because I am getting a new precision laptop that has only 2 USB ports, I acquired a Thunderbolt 3 docking station, a CalDigit TS3 Plus.  I now have the USB hub plugged into a USB port on the CalDigit, and the CalDigit plugged into the Thunderbolt port on the computer (which I did not use before).  I have the latest Thunderbolt drivers and firmware from Dell.    When I made the change, every device except one printer set up itself under the new arrangement with no action from me other than plugging in the device.  (I had to reinstall one printer.)  The mouse is also a Logitech MX Master 3.

        I have not had any issues with the mouse or any other USB device in the new arrangement, nor with the audio and some external hard drives that now all connect through the CalDigit.  I cannot figure out what is different about the keyboard that might be causing this problem.  I did search for the keyboard in Device Manager.  It is hard to be sure because there are several things there labeled Logitech keyboard, but I made sure all of them are set to not allow the computer to power down the device.  I know the keyboard stays powered on because it has lighted keys that are still lit.

        Any ideas?  Thanks.

        hmm.. Have you tried disconnecting other devices non-critical in this USB Hub to establish whether the Hub is at fault? By at fault, I mean not supplying enough power for all the occupied hub ports.

        It is a powered USB hub, and there is nothing plugged in that draws much power.   As I noted, I have used this same hub plugged directly into the computer with all the same devices for more than 2 years with no issues.   I first observed this problem a week or so after I switched the hub to the Thunderbolt docking station, although I cannot be sure that it is related to the problem.  As I noted, all the other devices on that hub (mouse, webcam, printers, etc.) have been working fine.  The fact that it is only the keyboard is what makes it hard for me to track down — unless the keyboard has developed an internal hardware problem.
