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?
- PC1: Asus P8H67-I board + i5-2500 + 120 GB Samsung 840 EVO SSD. Native VGA. Windows 10 Home
- PC2: HP Elitebook 840 G5 + i5-8350U + 8GB RAM + 500GB SSD. HP HDMI to VGA adapter. Windows 10 Pro
- PC3: Intel NUC8i5BEH + 2 * Crucial ValueRAM 8GB DDR4 SODIMM CL17 (2400MHz) + 250GB Samsung 970 EVO SSD (3400MB/s-1500MB/s). ValueLine USB-C to VGA adapter. Windows 10 HOME.
- KVM: Belkin Omniview SOHO KVM F1DS104Lea (4 port VGA+USB)
- Keyboard: Dell R17D30 PS/2 keyboard with Eminent USB to PS/2 keyboard + mouse splitter
- Mouse 1: logitech M500 USB mouse
- Mouse 2: logitech M705 wireless mouse
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.
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?
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:
- 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.
- 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.
