KVM = Mouse does not work from controlling side

I am able to see the monitor screen now from the controlled computer, but still have trouble to activate the mouse or keyboard of the controlled side.
I appreciate the help from Chuck but still cannot get it to work.
I am using an USB keyboard and an USB mouse on the controlled computer side and use a HP Notebook on the controlling side.
The notebook has a touchscreen and a touchpad. I am usually use a wireless mouse to work with it.
None of the features work with the KVM.

Now it works. Slow but, it does. No Idea what I did. But anyway: Thank you all the great help.

Do you happen to have multiple displays on the server side?

I just duplicated the displays. But just the regular win settings.

Did you check the documentation? Cannot control the mouse and keyboard - GL.iNet KVM Docs
What firmware version are you using?

I would try by disconnecting your duplicate display completely and just stick to a single display on your server PC to begin with to see if this would work.

Try a different USB cable between the RM1 and the computer for keyboard and mouse.

I had a similar problem. The cables included for keyboard and mouse on my RM1 units were 1 USB-C to USB-C and 1 USB-A to USB-C. I used the USB-A to USB-C for power, but my computers were older and didn't have a USB-C input for keyboard and mouse, so I had to supply my own second USB-A to USB-C.

Some USB-A to USB-C cables that come for charging devices are power only and one of them I pulled out of my box of spares didn't work because of that, so I had to replace it with a standard, fully wired cable.

Can you try the older 1.1.1 version? Release v1.1.1 release1 · gl-inet/glkvm · GitHub

I am not sure what you mean. I do have one physical monitor.
How do I disconnect y duplicate display?

Ups. I need to check the documentation and let you know.
Firmware is: V1.3.0 release 1

My Desktop also does not provide USB-C>
I checked my cable USB A to C. It works as a data cable.
Good hint, but it is still not working.

Sorry but I thought that you had duplicate physical displays rather than a single monitor+ KVM.

Please try the upcoming version 1.3.1, which fixes some keyboard and mouse compatibility issues
