XPS 15 9570 - Problems with USB keyboard

I'm having this exact same issue with my Dell XPS 15 9570, Dell Thunderbolt Dock TB16 and Das Keyboard Professional 4.

We have 2 XPS 15 9570, they both do it. Updated all drivers, BIOS, Firmware, Windows updates, different keyboards.

Nothing Fixes it.

Thank you for your message. How long have you been having this issue?

Does this happen if you bypass the docking station & connect directly to the notebook?

Have you tried different USB ports & did you observe the issue?

For my reference, please click on the message tab next to your avatar– click “New Message” & search for my Dell username (Dell-Sreejith R) & send a private message with the service tag, registered name & email address.

What is a Dell Service Tag and how do I locate it?

I have the same issue. Was any solution found?

I have a belkin docking station connected over usb3.0. My mouse pointer also freezes togethere with the keyboard inputs. It does not happen when connecting the mouse directly to the laptop.

I have also installed Hackintosh and everything works well in Hackintosh, so I suspect Windows may have some problem in communicating with thunderbolt or bios and thus causes the problem.

After restarting many times, I think I find the solution.

Go to BIOS->System Configuration->ThunderBolt Auto Switch. Disabling "Auto Switch" and Checking "BIOS assist enumeration" or "Native enumeration" both do tricks for me. Give it a try and hope you can solve the annoying problem.

My BIOS version is 1.7.0, but I think 1.6.0 should also work.

I tried this with BIOS v1.7 but it didn't work for me. I still have the problems.

I am also having the issue with sticking keys on the usb and bluetooth keyboards.  I have XPS 15 9575.  I have updated firmware on both laptop and docking station.  I have tried multiple usb ports and replaced the docking station.  The issue still persists.  Any help would be greatly appreciated.  

I also had this issue and on the advice of another forum member I disabled C-State control in the BIOS today (this controls the processor going into various power saving states when it is idle). This is different to speed step which alters the speed when the processor is in use. Seems to have done the trick for me but I suggest you do your own research.

From my limitied understanding it will likely use more power and may increase temperature a bit, but so far all good for me and no keyboard repeats.

Obviously it would be better if Dell or their partners could fix whatever is causing the issue in the first place.

same issue! is there a solution? 

Mine is doing the exact same thing (external keyboard)-- have tried multiple keyboards, with or without usb hubs, updated all the software, including firmware, erased windows and reinstalled, Dell has even replaced the motherboard yesterday and same issue.

My issue really comes out with an external monitor and the dell xps lid closed.  Keyvboooooooooooooooooo) will do that -- and may or may not even detttttttttttttttttteeeeeeeeeeeeeeeeeect an input

It's 5 years later, having the same issue. Anyone know what might be causing this? I've switched to a new wireless keyboard and new docking station but still happens.

Mine is XPS 15 9530
