Mouse and keyboard problems when using Belkin Omniview SOHO KVM F1DS104Lea with Intel NUC8i5BEH

[srepyuc]

I am having mouse and keyboard problems when using a Belkin Omniview SOHO KVM F1DS104Lea with an Intel NUC8i5BEH.

When I connect any of my 2 mice and the keyboard directly to the NUC (PC3 from the details below), everything works fine. For me that means all drivers are OK and I don't have an interference issue between USB3 and the wireless mouse.

However when I connect any of my 2 mice and the keyboard to the KVM and the KVM to the NUC then I get problems: 

• The mouse movement stutters every few seconds. Both USB and wireless mouse have the same issue
• The keyboard regularly looses a key press, or starts repeating the key I pressed.

I have tried most fixes I can find on the forum, tried to connect the KVM to all USB ports, connected the wireless mouse dongle to a cable close to the mouse, etc.... Nothing helps.

When I simultaneously rip a CD on a USB DVD-reader, the problem gets seriously worse; keyboard and mouse become practically unusable during the ripping. This additional DVD-reader/KVM interference goes away if I connect the KVM to the front-left USB connector and the DVD to the front-right one. But it does not resolve the regular mouse stutter and keyboard problems.

I have 2 other Windows 10 PCs connected to the KVM (PC1 and PC2 from the details below); these do not have any of these issues and work fine with the KVM. So the problems seem specific for the NUC8i5BEH/KVM interaction.

Any idea on how to solve this issue?

Thanks

Hello srepyuc Thank you for posting in the Intel Community. You are mentioning that the Intel® NUC works fine using the peripherals with straight connections this means that the Intel® NUC is working properly, now you can try completing the drivers and BIOS updates if you have not completed them (reference link: https://downloadcenter.intel.com/search?keyword=NUC8i5BEH) you can also try Intel® Driver & Support Assistant (Intel® DSA) https://downloadcenter.intel.com/download/28425/Intel-Driver-Support-Assistant?product=128824. If the behavior still persists after the updates this could be a comparability issue between the Intel® NUC and the KVM. Bear in mind that we have not validated the Belkin Omniview SOHO KVM F1DS104 Lea with the Intel® NUC so we cannot guaranty that it will work properly on the unit, you can find more information in the Intel® Product Compatibility Tool (http://compatibleproducts.intel.com/ProductDetails/ExportPeripheralInfo?moduleName=Intel%C2%AE%20NUC&productType=Kits&productName=Intel%C2%AE%20NUC%20Kit%20NUC8i5BEH) for more details about validated peripherals. Hope this helps. Regards, Leonardo C. Intel Customer Support Technician Under Contract to Intel Corporation

Hello Leonardo,

Thanks for your help.

According to the Intel Driver & Support Assistant, my system is up to date.

I no longer connect my wireless M705 mouse to the KVM (it was on the KVM-build in hub). With only the USB mouse and keyboard connected to the dedicated KVM USB ports and the KVM connected to the front left USB connector on the NUC, the system seems a lot stabler. The keyboard no longer gives any problem. The mouse stutter is also improved a lot; I will need to work with it for some more time to see if it is still a real problem.

I will then probably connect the wireless mouse directly to the NUC, which will be my main computer.

Kind Regards

Hello srepyuc Thank you for the information. We recommend testing the system with straight connections (USB to USB), because this behavior could be caused by the adapters on the configuration.

Hello srepyuc Thank you for the information. Have you test the system without the adapters? Hope this helps. Regards, Leonardo C. Intel Customer Support Technician Under Contract to Intel Corporation

Hello Leonardo,

Thanks for the help.

I am not sure which adapters that you are referring to.

Currently the only adapter is the one from the PS2 keyboard to USB. Should I use a USB keyboard instead?

Kind Regards

[Leonardo_C_Intel]

Hello srepyuc Yes, that USB to PS2 adapter, if it is possible try a USB keyboard and mouse. Regards, Leonardo C. Intel Customer Support Technician Under Contract to Intel Corporation

Hello srepyuc Have you been able to test the system with a USB keyboard and mouse? Regards, Leonardo C. Intel Customer Support Technician Under Contract to Intel Corporation

Hello Leo,

With the PS2 keyboard and PS2/USB adapter it was almost working fine; I only had minor mouse lagging issues. I replaced the PS2 keyboard with an USB one (Microsoft Comfort Curve Keyboard 2000 v1) as you suggested, so that I only have a USB keyboard and USB mouse connected to the KVM. With this configuration I don't seem to have any problems any longer.

In order to compare, I reverted back to my original configuration that caused serious mouse and keyboard issues two weeks ago (so wireless mouse and PS2 keyboard connected to KVM). Great was my surprise that this configuration now also works flawless! I see only 2 possible causes for this:

1. Last Friday, the Intel Driver & Support Assistant popped-up and proposed 2 updates. A Bios update and I think the other one was a Wireless driver update. I installed both.
2. I moved the NUC. It was previously standing on my desk next to the KVM. Now it is hanging at the back of my DELL screen, 20 cm above the KVM.

Today the DSA upgraded itself and is proposing 2 more updates. I will see what that gives.

Best Regards
